BG - Eat At Tables
It's more than that, really... the problem here isn't the fact that they don't use the table, it's the fact that they go and do things the closer they can to Sims they have a friendly relationship with even if it means going 3 floors up from where they grabbed a drink, getting naked, and drink it in the bathtub.
Yes, it is a feature and they even bragged about it once. Sims purposely decide to go and have dinner on the sofa because the cat they have a friendly relationship with is sleeping on it.
This would be nice if it were based on traits, but it's not... so I tuned it down and so far, my sims have been using the table even if their friends are watching TV on the sofa. I wasn't going to share this one, but since someone asked for it, here you go.
