I'm sure a lot of it depends on where you live, in Shades case, the Bay Area, its hard to get people to even blink about most stuff anymore. Sioux Falls, perhaps not so much.
But stores are really hurting for money, for sales of any sort right now. I'd have a hard time turning away any business these days. Besides guys buy stuff for women all the time, just act like you know what you are doing, the bumbling routine only attracts attention.
And thrift stores rock, you just have to keep going back as sort of a habit, good stuff don't last, but it does come through.
