My father is a retired optician. He owned a very large business and there was no problem asking for this, repairs, adjustments, etc.
It actually makes me sad that people have resorted to online, but its the way of the world I guess.
I go to a very small place. Exams are done twice a week. I cannot say enough about how great the opticians are. They always remind me of what my insurance covers, have many frames within that range. Since I am allergic to silicone, they have a stock of non silicone nosepads for me and anyone else.
