Just then, some rich middle age guy comes along with this beautiful girl about half his age. "Well," he impresses her with contempt in his tone for what he's looking at. "My "Moonrise" was around $200,000 and it is much, much better than that one."

Typically the kind of vulgar behavior we can expect from this kind of guy... I hope he left the price tag on the print to show his "friends" how much he loves art... You did the right thing by ignoring such moron.
