Lonerism, as one who works in security and went to college for Policing, I know a fair amount about profiling and loss prevention.
Unfortunately, the first thing that they teach you is 'trust your gut'.
If one of the undercover loss-prevention people spot someone looking nervous or anxious, they hone in on them like a moth to a flame.
It's just that simple. You feel anxious, thus you look anxious. You're probably not a professional actor, so I'll bet that your palms get damp, you swallow too often and too loudly, you're always breathing heavily, looking around for threats...
Unfortunately, 99% of 'normal' society won't know how to interpret those signs as symptoms of what we face.
As for how you should present yourself... dress as if you're going to a job in a casual office setting. No tie or ultra-polished shoes... but put on something one notch above the typical style worn by customers in the shop you visit. Or four notches above in the case of WalMart.
Second, drown out your surroundings. Bring an MP3-player loaded with soothing melodies. Try to focus on the tunes as you're cruising the aisles. And just look at the goods, not your surroundings. The more you look around, the more people are going to SEE you looking around, and that'll raise a flag.
Third, if the above two things still don't work, and you find yourself being followed around again, or out of the store, then CONTACT THEIR SUPERIORS (via e-mail of course). Tell them about the repeated harassment that you're facing, and that, as a LOYAL CONSUMER TO THEIR STORE, you would appreciate if their staff didn't blatantly infringe on your human rights by constantly (silently) accusing you of theft. Also, threaten them by saying that, if that pattern of treatment continues, then you're going to go to the media and pursue legal action.
Really, you might not think that last course of action would do any good... and you'd be incorrect. Store policies change all the time, and for establishments that supposedly take pride in their customer service, doubly-so.
Oh... and don't use the self check-out areas. Only thieves and old people use those. 😉
First of all - thanks for the "insider" perspective. In some ways, I was somewhat hoping to hear from "the other side": i.e. employees and security - at least if the feedback was gentle and constructive (from what I've seen and experienced - security/LP sometimes come across as callous and as possessing a bit of a bully-mentality).
As far as what signs of anxiety I might display - well, I'd like to think that I often do a decent job of concealing much of it. "Sweaty palms" are not a problem for me - and during most of the moments in which I'm profiled, I don't think I'm exactly this shaking, quivering mess. And I think I learned a long time ago to avoid looking at employees or other customers; generally-speaking, I don't directly look at employees. I have a habit of "taking note" of them using my peripheral vision - if I fear/anticipate them targeting me....but I'd like to think that my perhipheral vision or "corner of the eye" glances aren't obvious or visible. If they do pick up on my covert observations - then chances are that they already were observing me closely.
Believe me - I've paid dearly for many of the times when I was caught looking at an employee - although these glances had nothing to do with trying to shoplift. On a few of these occassions - I simply wanted to see if employees were treating other customers like they were treating me....I was looking for evidence that employee suspicion wasn't limited to me. Well - these efforts backfired; my observant behavior was quickly noticed, and I was apparently assumed to be a thief who was "casing the store".
And recently, I just happened to make incidental eye-contact with a grocery-store employee (because these things just sometimes innocently happen) - and he stared at me as though I were a dirty thief. It seemed that he already had it in his mind that I was suspicious; therefore, what was supposed to be a quick glance that he shouldn't have noticed was prolonged into a little bit of a "staredown". Just a few seconds later, I noticed an obvious LP agent hovering around me; amazing how that LP agent just materialized out of nowhere.
There is obviously some "system" that is used in which employees communicate to each other about what "thief" to watch. (Look for employees who are wearing earpieces - that can be a clear sign that such a communication system is in place.) The employee who misinterpreted my glance "sicc'ed" the LP agent on me, seemingly.
Okay - I'm going to try to wrap this post up because it's already getting too long (I'm afraid that I'm just not a very concise or efficient person - sorry, everyone!)...but "dressing up" to go to Walmart or to the grocery store is apparently too difficult to manage for me....otherwise I would have made it a habit by now. The flexible "warmup pants", t-shirt/sweatshirt routine is more comfortable for me than putting on "stiffer" clothes. Besides - I am sometimes dressed a little more nicely - and it often doesn't make much of a difference. Sometimes, there might be a slight difference - where instances of employee suspicion may be decreased, but it never seems to completely go away. Other times, there is NO appreciable difference - whether I'm dressed "down", or dressed more nicely. In places where my "dishonorable reputation" seems to be firmly-established and I seem to be on a "list" of people to watch...how I'm dressed wouldn't matter, anyway.
Besides - aren't employees supposed to be focusing on specific behaviors - as opposed to how someone looks or how they're dressed?
There is something else in your post that I want to address more privately - you may get a PM from me in the near future, if that's o.k..
