I don't disagree, but there are ways to do it and ways not to do it. In 25+ years I've never been called on the carpet and I run a fairly low balance, even negative once.

If you choose to not use your head expect to have to put up with the hassles. I personally think the union should let you swing if you're too dumb to figure out how to navigate that obstacle, they have much larger, legitimate fish to fry. You're just wasting dues money at that point. As for worrying about snacks from a galley cart, I don't share your concerns. I'll buy my own.
