I went in to Optical Gallery to see if they could repair a pair of Ray Ban sunglasses that I had purchased at another store. They stated they did not do repairs but asked to see the glasses. When they realized it was just a missing screw they told me they could fix them.
I left my glasses and came back the next day to pick them up. Not only did they do a great job repairing them, but when I asked how much I owed they stated "no charge". I couldn't believe it and will buy from them in the future.
