Oops, I keep forgetting that one of my household sims is vegetarian. I wish the warnings were a bit clearer because he just goes ahead and eats stuff then gets the bad moodlets about it.
When I have vegetarian and non-vegetarian leftovers in the fridge, if I just click 'get leftovers' or autosolve the hunger need I wish my vegetarian sim would autonomously choose the vegetarian option and not eat meat then get the moodlet and make me feel awful about it. I rarely have meat around for that reason but sometimes I want the other sims in the family to be able to have some and this makes it really difficult.
