Reposting an earlier comment about a flight last SAT from MEM to home on DL's commuter airline, a CRJ 200. I had a boarding pass for this flight, generated from the fact that I was on the previous flight as a PM and was upgraded. I gave the FA the coupon on the boarding pass for a free drink and asked if I could take the wine home as I did not want to drink it before driving. She looked at me and said, "I cannot accpt this because you made it at home." While a senior I am usually rather good on the uptake and while looking at her in an odd way she said, "just kidding." Well, I praised her for not letting the job get her down and praised her once agian in front of the pilot for her great humor while leving the aircraft.
