UPDATED: An update: went back in, same crappy staff attitude.
1. A reason you might suspect this store: all the cases have ""Please do not take pictures"" written on the glass in black sharpie.
2. All sunglasses have the price tag well-taped in place to cover the model / style number. I interpret this as they try to make it difficult to figure out exactly which model you are trying on, lest you go home and realize how much cheaper the sunglasses can he had ordering from Amazon, etc.
I had no luck getting help with a hinge screw that came out. I was told ""look up their number and call them"" -
I guess my $100 sunglass purchase wasn't worth any post-sale effort. I'll duck in here once in a while to look, but I'll go elsewhere to buy.
