That is interesting. Wonder what effect it would have on you if you took it again?
I'm not rude, per se. But I make jokes and say things that aren't appropriate.
For example: I was on this job a few years ago and this woman dropped something heavy on her foot, so I joked, right in front of her boss and the person who was paying me to be there(the person who owned the business), "well there's a lawsuit"! And then everybody got terribly uncomfortable.
The irony is, a year later that woman did end up scamming the business out of a lot of money.
Was it the joke that bothered them or the lack of concert for the woman's foot? Maybe you're just surrounded by people with no sense of humor. I guess it depends on the situation, if someone's seriously hurt it's not the best time for jokes but otherwise people should't get offended so easily.
