BTW, if you're not dressed properly, some high end stores have a security guard who won't let you in. This can get tricky these days, as many wealthy people dress like slobs.

I once wandered into Cartier's in NYC, dressed in my trademark slob clothes. The security guard tailed me about a foot behind me, obviously trying to intimidate me into leaving. I just kept me hands in me pocketses, took a look around, then left.
