Join Police Academy!! If only there was one.
I wonder if I'd still have social anxiety if I had AUTHORITAAAAA!
Seriously though, maybe like work in a garden center / plant nursery. I did that over summer once. There were some awkward moments when people asked where such things as point settiers are. WTF is a point settier? I still have no idea. Once I pretended to not speak english, I think they bought it but the embarrasment has burned itself into my permanent memory for _ever_. Then I learned to just point them in a random direction, as politely as possible.
Mostly I got left alone, and never once did I get put on checkout (everyone else _wanted_ to do that to avoid the manual labor).
I'd never do it again though, the pay was shit.
