Not too long ago we stopped to eat at a restaurant on the way to visit our son and when I was eating the mashed potatoes I felt something hard in my mouth. Took it out and it was a piece of wire from what I would call one of those metal scrubbing pads. I showed the waitress and she was horrified. When I went to pay my bill, she turned to ask the manager/owner what she should do about my bill and he just shrugged, finally said to take ten percent off.
I told her she could tell him he got off cheap as if I had swallowed that I probably would have been in the hospital for surgery and he would have had a bigger bill than ten percent off my meal. Also told her she could tell him I wouldn't be back and would let everyone know of his attitude and the quality of the food. If he hadn't shrugged his shoulders and had the attitude he did I wouldn't have reacted in the manner I did as I know accidents do happen. But instead of being apologetic, his attitude was almost beligerent for me finding it in my food--pardon me I didn't cook the food and certainly didn't bring the piece of metal in with me! It takes all kinds, and some we could do without!
I have had all kinds of food experiences in other places, but most of the time they are very apologetic and concerned, it's the ones that take the attitude of 'so what' and also act like it's your fault, those I lose patience with very quickly.
