Doesn't care about regular customers

We used to be regulars at Ray's Place. And when I say regulars, I do mean regulars. Living just down the street, we went there several evenings a week for a bite to eat or a drink. The wait staff and Ray, the owner, all knew us. Several times we had ordered the wings and they arrived undercooked and had to be sent back. There was more than one time that we felt sick after eating there. Yet, we perservered. The final straw was one night when we went on a night when they had a burger special. I bit into the burger and into something hard. I pulled the burger apart and there was a cooked piece of plastic in the burger. When I complained to the wait staff, the burger was taken away with apologies. Soon after that, Ray came over with a tray of raw burgers to show me that they had a sheet of acetate overtop of each burger for storage in the fridge, and that the cook had neglected to remove it before cooking. Obviously!
What I needed was not a demonstration of the obvious, but a show of good faith to a regular customer and a complimentary meal. But no, we got charged the full $3.50 for the meal. Yes, that's right, he couldn't even swallow a $3.50 charge for a plastic burger. That was our last visit to Ray's.
