OK.
Well, I'm a security officer or as what you'd call a "rent-a-cop". Now, I don't know where you live, but it sounded kinda wierd there was a security gaurd in a mcdonald's. Or was he from the movie theatre? Anyway, if he does security at the theatre, and it's not mall security or whatever, he shouldn't have been in the mcdonald's to start with. I don't like the name calling and crap i get but i haven't lashed out at anyone like this guy apparently was.
When i'm on duty, My job normally consists of watching the parking lots for break-ins, fights and other bad things like that, and sometimes i go check the locker room for break-ins to the lockers(i'm normally working at recreation centeres).
there are also rules about no skateboarding or bike riding on the sidewalks of these places so SOMETIMES i'm a jerk to the kids doing that but they ARE breaking the rules and there's a skate park right next door so they could just go there.
Sometimes you have to be rude to get your point across, or "escort" someone off the property, but i haven't had to yell at people like your security gaurds, i just tell them the rules, say what part of that rule they're breaking and to bugger off or i'll have to MAKE them bugger off.
So i agree those guys weren't really doing their jobs, but you didn't have to go off on the first one quite so much.
