I'll admit i was a little weirded out to see these guys on campus the first time, but it seems to be gaining momentum. I'll also say it appeared the females were getting way more enthusiastic responses than the dudes. Mike has also got a great point about rent a cops. Some of those guys have pretty warped senses of power structure. They don't even have real badges, just patches!
At the mall near my house, they actually roll on segways and look downright silly. This one guard had a serious Napoleonic complex one time back in highschool (He was shorter than I even on top of the segway and wearing a nonstandard issue Mountie style hat, and started yelling when it wasn't needed). A friend was waiting near the movie theatre and waved to me to get my attention. I was dressed like a fool and this probably prompted the confrontation. (I had on shorts fashioned from my lil bros halloween pirate costume and a bandanna messily holding my hair, we weren't going out to meet any dates so i didn't really care)
Anyways segway guard zooms in to my friend and immediately demands he leaves the premises on account that gangs are not allowed at this mall. My friend (who is dressed rather conservatively) is astounded. He says, "What do you mean gangs?" The guard says, "Don't try and fool me, i saw that gang sign you just flashed to that other guy (referring to the wave)" My friend bursts out with laughter as this claim is pretty absurd. I continue walking up to my friend to see what all the commotion is and the guard yells "Stop right there don't come any closer to me!", I didn't heed much warning and walked within normal conversational distance. The guard then asks what drugs I am on. I get pretty pissed off at this accusation and demand to see a manager. He then calls the police and my friend and I go to another movie theatre as to avoid the hastle.
Come to think of it, maybe we were meeting dates, because mall movies are always a lot more expensive than other theatres around here, and we're pretty cheap dudes.
Moral is, some would rather yell and piss and moan about a situation they don't understand rather than calmly converse in order to resolve a situation. This goes for both parties in my case as the guard was acting rather ridiculous, and i got pissed and started yelling when accused of drug use as opposed to trying to get through to the guy.
Wouldn't want you to land in the same boat at the mall.
