- Military-level strategizing over how to eat the most expensive food to get the most for your money, often punctuated by comments about how you have to 'beat the house' or 'avoid the decoys' of cheap items like bread.
- Rules-lawyering over what 'all you can eat' really means. The restaurant might argue, for instance, that an extra crumb is food the customer didn't eat (and is obligated to pay additional money for). Or they might refuse to let a customer leave until they've really consumed ALL they can eat.
- Customers going to extremes to eat as much as possible (fasting before going; staying in the buffet for absurd lengths of time, sitting or even standing right in front of the buffet), sometimes even eating all the food and leaving others hungry.

- Dilbert has done several of these. In one strip, Dogbert and a buffet waiter got into an elaborate argument over whether or not "all you can eat" applies to food that you take but don't eat.

His family didn't even realize what he'd been up to until June of 1996, and all evidence suggests that he's still there today.
