IamA Optical sales associate, I can prevent you from getting ripped off. AMA!
I am an optical sales associate, which means I sell glasses for a living. I've seen some crazy things that you wouldn't think exist in the optical sales floor, but I've also seen some crooked deals happen in a previous job. I can help you from getting ripped off next time you go buy glasses. AMA! :D
EDIT: gaaaaaah!!! SO many questions >.< trying to get to them all
EDIT 2: I did not expect this to blow up, I had to take care of some things D: Reading what I can >.<
EDIT 3: Alright Reddit, it's been a hell of a day and I answered questions for about 2 hours straight xD hoped I could have been of some help to you guys! I'm gonna enjoy the rest of my day off now!
