A: Have you been to this club before there before?
B: Of course.
A: (irritated) Oh...well.

Sorry for posting this again, but its really important for my assignment:

Would you ever use "of course" in this context or could you imagine that a native speaker would use it like that?
I think in this case "of course" can come across arrogant and snobbish(sth like "Yes of course I have been there,how can you ask me such a stupid question") and a native speaker would rather use sth else(eg. "yes,indeed") to confirm that he has been there before, do you agree? And do you think I could consequently call it an ill-formed utterance, because it doesn't obbey the rule of a native speaker grammar?

I appreciate every kind of help! THANKS!
