I beg your pardon?!?

Back to the OP: sadly, customers rarely apologize if they make a false accusation like that. Maybe it's because they're too embarrassed to admit they made an ass out of themselves that they can't bring themselves to *gasp* aplogize to a retail employee - of all people.

Or they could simply be assholes who are stuck in their own bubble and think they are right all the time.

I vote for both.
