Visiting from Vancouver, went to skybar, front door security guard checked my purse which was a cute little sparkly backpack style purse, went upstairs to dance... having fun until some random bouncer told me to go check my purse , I stated no it had my money, phone, ID, including passport; so pretty much all my identity. I asked why the guys with shoulder bags, fanny packs and other purses were okay.. he said it was different... really... how so? I was then asked to leave if I wasn't willing to check my purse. So I left. Needless to say I am not amused. Maybe management should have a sign or indicate that bags are to be checked instead of throwing people out for apparently no legitimate reason.. never coming here again... just sayin!
