Then there's the other side...

Back in the late 1970s, had a non-rev accuse a flight attendant of stealing liquor minis from the 1st class galley. He reported it to me and I passed it on to the captain.

He, the passenger, saw something he thought was theft. The F/A in question did take some minis from first class to sell in coach because they ran out of what they needed.

The captain quickly got to the bottom of it then told the passenger to go ******* himself. We never heard anything else about it.
