Not quite a DYKWIA but my wife , my GS companion, was waiting to board a recent flight and a lady crowding the boarding area clearly annoyed when they called for GS, and my wife said excuse me as she boarded
the lady said really really loudly,

“you go fancy lady”, she then proceeded to drink several glasses of her preferred wine , spilling the last glass, and being really rude to the flight attendants

my wife proactively complimented them and wrote a letter in their support
