I had a slightly unpleasant experience in Hermes today, actually, and I think it was based on two things: what I was wearing and my youth (I'm 25).
I'd received a scarf as a gift from a client but I felt that it was too old for me so I took it in to exchange. I was wearing nice jeans and top, my Chloe bag, and nice flip flops/jewelry. I didn't look like a millionaire, but I didn't look like a bum, either. However, the clerk I initially spoke with was disdainful and rude to the extreme. She barely spoke to me and acted like I was trash under her feet. She asked if I'd seen anything I liked and I said I was looking for the moment.
She brought me my store credit and couldn't have walked away fast enough.
I wandered around the store for a bit because I wasn't entirely sure what I wanted (well, beyond a Birkin, which I can't afford!!!!) and ended up back at the scarf counter. This time, a very lovely woman asked if I needed help, had suggestions based on what I said I wanted it for, and I ended up a very happy customer with a beautiful Belles du Mexique scarf. I even bought a bracelet, though I hadn't planned on spending a lot of money there!
I just wish that first lady was nice to me because it did sour my overall experience. I don't have a lot of disposable income now (25 and in an arts job in NYC) but there was no reason for her to treat me so poorly. She's a clerk for crying out loud! Anyway, just wanted to vent. It apparently can make a difference what you wear and how you're treated.
