It's weird. I read this thread a few days ago and then today had reason to think about it - in a very bad way.
I had the day off and met a friend at an area mall for lunch and a little retail therapy. After lunch we went into Sephora to check stuff out - she's just starting to get into makeup (post-divorce).
There were plenty of SAs in the store - I'd guess at least three, maybe five. I walked over to the perfume wall and started sniffing, while she checked out the Urban Decay and a few other lines.
We're basically about the same - middle-aged women who weren't carrying shopping bags or anything "suspicious." My friend wasn't even carrying a full purse, just a wristlet. Yet she had a SA pestering her - and not in a good way - every minute she was in that store, while I was left to browse alone after declining help. After we left, she said it seemed pretty clear to her that they felt they had to keep an eye on her. And she's NOT the type to be hyper-sensitive about that stuff.
In case you hadn't figured it out, I'm white, she's black.
The ironic kicker is that until a few years ago, she was a prosecutor in misdemeanor. Handled a LOT of shoplifting cases.
