Why does Molly Bloom's search people?

I was recently at Molly Bloom's (the bar in downtown London, Ontario), and was surprised when I noticed the bouncers rifiling through a female associate of mine's purse.. I thought "Maybe just the ladies get their purses searched, since they always so many bad things in them", before I knew it I was being searched too! I had to take out my keys and everything, and it was a Thursday!!! So to teach them a lesson we threw ice cubes at each other until we were asked to leave (after spending all kinds of money). I've never been searched going into a bar in London that didn't have a big-name band playing (that I recall).
