Yeah it’s unfortunate that’s why we either split it or specifically say hey I want some too. We’ve had it where we had left overs and he’d eat it or make something and eat it and I’m like dude why don’t you leave some for me and he just didn’t think.
If you know he has a big appetite, why not just order 2 sides - 1 each to save any arguing?
Definitely an ick! My spouse always makes sure I eat well
