I Purchased over $1000.00 worth of glasses at Lakeland, Fl Lenscrafter on Florida Ave & the left lens kept coming out, would not tighten. They refused to give me a screw to take with me when it works out. But they would allow me to drive almost 18 miles without my required glasses in heavy traffic for them to put a screw in. What is the thinking behind this? A two cent screw cost them a customer for LIFE! Plus the laminate on my sunglasses lifted off the lenses and they could have cared less. A screw of all things!
