I agree with the previous comments. I recently went to purchase glasses and was completely ignored for 30 minutes; the store was not busy at the time. When the tall gentleman finally helped me, he looked very aloof, as if my presence was an irritation. I decided to take a closer look at him, and although he was wearing a suit, his shirt was dirty - as if it had been worn several times. The lady at the counter was not friendly either.
Needless to say, I decided to take my business elsewhere. I'm unable to rate the quality of their product, but the general attitude towards customers gave me serious doubts about customer service after the sale.
