Does This Bother You?

You are at a restaurant with a friend and after your food arrives and you have eaten a few bites, your friend calls the waitress/ waiter over and reads them the "riot act" (in her outside voice) about a problem with her food. The waitress/waiter apologizes and offers to take the food back and bring a replacement. Your friend is rude and not accepting the apology, but she says that she will try another serving. That order comes; she doesn't even thank the server; she eats this serving; and then, loudly, says that she isn't going to leave a tip and will probably NEVER come to this restaurant again!!! You want to crawl under the table from embarrassment!!! If this were a one-time occurrance, you could maybe accept it, but it has happened before, so you decide to NEVER go out to eat with her again. I don't know about you, but when I am out to eat, I feel very lucky to be fortunate enough to be there. On occassion, you may get a meal that you are not happy with, but there is a way to handle this that doesn't involve being rude to anyone. The wait staff is the most accessable and often takes the brunt of the situation. If you have ever worked as a waitress/waiter, you know that it is a hard job with little pay. I worked as a waitress in High School and in college and should have written a book about all of the experiences I had, both positive and not-so-much. Now, when we go out to eat, I find myself tipping even more than suggested because I know how hard they work.
Does a person like the friend I described above bother any of you? How have you handled this situation?
