I'm probably screaming at them to just eat the food in front of them (in stronger, not forum friendly, wording) too. Like I don't care if it's burnt there's food in front of you just eat it. Stop whining. I have no patience for my sims incompetence.
Thankfully I don't have new sims very often to worry about. It's all long running games and everybody is very good at cooking after so long. Except Alex. He still can't even microwave hot dogs. But his wife is a fantastic cook so she does all the cooking. Or the butler when she's not around because the kids should not eat dad's cooking. :/.
