I had a table of five tonight.
When the daughter goes to eat her salad there's a piece of ... something ... in her rolled silverware. Which is icky, I get it, so I apologize, take the offending set away and bring out a fresh set immediately. Everything fine after that, they eat their salads, their food comes out. Everything's great. In point of fact, they tell me I'm "wonderful".
The daughter eats everything on her plate, and even mentions how stuffed she is. I bring out there bill, and go. I come back to check on them, and they ask to see a manager, but "Not to worry; it has nothing to do with you."
I figure fifty/fifty chance of a complement to the restaurant or something wrong/disgusting in the bathroom, and go get the manager.
Turns out that the silverware issue was "disgusting" (I agree there...) and "ruined her daughter's meal" (wait, what?) and their server "never brought clean silverware" (So, they ate with the dirty silverware?).
So my manager voids the daughter's meal, because she can't just call them liars to their faces. Well, I can certainly say it on the internet: They are lying liars that lie!
So I take out their new bill, smiling my fake I-want-to-yell server smile and tell them to enjoy the rest of their evening. When they state again, "Don't worry, that had nothing to do with you."
HOW DOES THAT HAVE NOTHING TO DO WITH ME!?! Aside from the fact that they, you know, blamed me, I now have a void under my name (which are inevitable, but can cause problems if you get too many), and, if my manager had believed them, and if she thought it was a large enough breach in customer service, could have gotten me written up.
TL;DR: Woman tells me not to worry as she uses me as an excuse for a free meal.
EDITED to fix spelling.
