@gilboston,
I don't think I've heard anyone say they drive better when they drink. Also, alarm clocks fail too.
Anyway.....let's see, let's see....
Oh, I know, when you say something to a clerk in the store, such as "I'm looking for an 8 inch flubinator, with a battery backup, do you have those?"
and they say "What?" as in they didn't understand/hear you.
Depending on the reason I preceive they did that, I've been known to say "you heard me" or "Tell me what you did hear, and I'll fill in the part you missed.
