From today's Dear Abby - A woman is annoyed that her father, during any kind of celebration where food is served buffet style, takes all the "good" parts of casseroles, all the top of somethning with yummy baked cheese, crunch onions off the green bean casserole, and so on. And gets offended when the LW speaks to him about it, and also says her mother refuses to get involved. And that guests will make a beeline for hte food to get there before him.
DA gave 3 suggestions: make him his own, stop serving casseroles, or plate the food in the kitchen.
For once, I agree with all of her suggesetions, although if it were me, I'd skip giving dad his own as it would reward his bad behavior. Although evilsiamesecat might be tempted to embarass him "hey Bob, leave some for the rest of us, ok?" or something along those lines, but that's why she doens't get out very often!
