A few years ago I heard an interview with three guys who had written a book. Two were waiters, and one was maitr'd at some of the fanciest restaurants in New York.
They said, you don't want to get sideways with the wait staff at a restaurant. You say your steak is too rare, you send it back. That's OK.
They bring your steak back to you, you say it is too well done and you demand a new steak.

These guys said, you will get some "secret ingredients" in your new steak.
