I think it'd be nice if we could have a toggle/checkbox (like prisoners for food/no food) akin to "Eat in dining room/area" which will always force the pawn to go to the closest(in case you have multiple) dining area.
I find it very frustrating that you create nice dining areas just for your pawns to not give a shit and have a nice picnic in the middle of corpses with no picnic, no table or blanket. Even if you create multiple dining rooms this still happens.
It being a toggle makes it so you can have pawns that do long distance hauling or hunting to not abandon their duty and eat on the spot (if you so desire) just as it is now.
I'd happily take the time loss over the mood loss for eating between a bazillion corpses.
