I always try to avoid complaining about service until after my meal has been served to avoid any unnecessary and unordered "add-ons." However, when a young server says to me, "Not a problem" I always want to respond with, "I would hope not" complete with a great big cheesy smile. I usually don't.
I'm not as bad as a former co-worker. She consistently ordered water without lemon and always added, "If I wanted lemonade I would order it." Boy did she throw a fit if they accidentally forgot and put a lemon in her water. She would make them go get her a new glass of water, sans lemon slice.
Another co-worker would ask for something, and if the server didn't ask the table as a whole if there was anything else she could bring, he would ask for a second item when the server returned with the first item, stating to the server, "Use your head or use your feet."
I have an Italian friend who used to own a restaurant, and when going out to eat loves to teach/point out to servers waiting on our table how to open wine, pronounce words, how to serve, etc. etc.
So you see, some customers can be just as dreadful as some really bad servers. I guess in the end that is my biggest pet peeve -- eating with people that exhibit such bad behavior I have to sieve my food to make sure I didn't get the loogie meant for them.
