to assume if someone says they're cooking dinner..

[bouncingorange]

that it will be ready at your usual dinner time and not 10.30 - 11pm? Selfish arse.

YANBU. So pleased you didn't wait.
Silly man.

Yanbu, not sure why you're getting such stick I would be pretty pissed off in your position.

I'd be annoyed if someone said they were going to cook and then expected me to wait until that late to eat (if you normally eat earlier). It would spoil the meal. If he wanted to watch footy he should have got the meal ready in time or not offered.
