I took an elderly lady to get new eye glasses at Costco, the lady that helped us pick out 2 pairs never smiled, and was curt, she was choosing to show us the most expensive frames, even after I said we wanted something in a lower price range. When we finally picked out 2 pairs, she sat us down, and got our information etc. asked how we would be paying, I said Master Card, she said«We only except American Express». I said I guess we’ll be going elsewhere then, thank you for you time, she said nothing.
