That was my understanding as well. Even if you were able to surreptitiously slip an FA a tip, wouldn't there be a risk of other people around you wondering why you were getting free drinks while they were asked for payment or an HOOU? I can't see an FA risking their job by giving away stuff they're supposed to be selling for a few dollar tip.
