Yes, but only for serious things.
For example, my husband and I went to a place in Portland, OR, and he found a sharp bone in his boneless chicken burger. So we told the waitress, and were going to bring out another one. Then, while waiting for the replacement, he found a hair in his fries.
It was a shame, because it looked like a nice place, but it was a bit much. The hair alone wouldn't have been that bad, but add the sharp bone, and it becomes a safety thing.
We never ate the rest of our meal, we just left. The owner was nice enough to give us a gift certificate though, but living in Canada, we never used it.
