Recently, on a flight to OGG from Denver, I asked for the tapas box and a glass of red wine. FA says "credit card". I say; "I am 1K". She says: "There are no 1Ks in the economy cabin". SO I pull out my paper boarding pass and hand it to her. She says: "Wow, it says your 1k". And heads off to first to get a knowledgable person to say grace over my boarding pass. She took it with her.
She comes back and harrumphs at me, and gives me the tapas box and a glass of wine. I mean really; what a scene. But I have no reluctance to ask for the free stuff.
