I find your lack of restraint disturbing Seriously, how can they be ignorant of social customs? I'm standing next to the soda fridge right now at a local pizza chain place waiting for my order. I know I should eat better, but I'm not. No excuses, it's on me. Anyway, there's a mom with three kids that keeps treating the sample plate as their own personal food. The kids have each gotten two or three small pieces, then the mom finally tells them to not eat so much? Where was she two pieces (each) ago? That normal sized pizza was meant for many people to take one small piece of if they had to wait a bit. Out of that normal sized pizza, half of it is gone thanks to this family. I swallowed back the urge to ask her if she understands the social norms regarding how to behave around "sample food". Then if she said she did, ask her what excuse she's got for not keeping her kids in line. I'm a father, I know it can be done. Just like working out it takes discipline.
