Since nobody has really said anything here in the comments.

Things I have noticed :

- If the options don't show the first time you click on it, try clicking on one of the little pots around the main foods.
- The "everyone eat" option will pull EVERYONE, regardless of if they're already eating or not hungry, they'll drop whatever they're doing and swarm like ants on turkey.
- If something goes rotten, say, the turkey and salad have gone off but the jelly is fine, sims will autonomously hit the "everyone eat" option in an attempt to still get at it, causing it to queue up an awful lot. 8-9 times if you're cancelling it, as when they can't pick it up, they hit it again. I've stopped serving before the maid comes round, because she just spends 90% of her time eating. (I don't know if that's just her, though, I have noticed other people finish their meals and instantly get up for another)

Overall it's a good idea, but it's probably a few expansions out of date and could do with some love. More limits on the”Everyone Eat” option would be great, “only call if <60% hunger/not already eating” and such. I'd also love to see my customers wash their own plates -_-;
