I can attest to this. My wife and I went to Paris for our honeymoon years ago. She took high school french and I didn't know a word. Our waiter was pretending not to know English until my wife ordered me penis instead of rabbit. He burst into laughter and then took the rest of our order in English.
I should mention that I've attended the funerals of both my wife's grandmother and my Aunt in the last 10 days.
