I have become shameless. If Milanos or those other tasty cookies appear, at least two or three - alright, I'll admit it, four, count 'em, four packets find their way into my carry-on. I'll usually take a banana for good measure as well.
OTOH, I rarely drink at the club any more, so I think they're making out. Actually, considering how little I make use of my lifetime membership, they're making out no matter how much I drink.
