Can we fine tune the eating/seating behavior, please?

Speaking of weird places to eat: When I tell my sims to eat and then go to the toilet, more often than not they actually understand what I'm trying to say - eat first, poop later. But sometimes they feel so talented at multitasking that they just take their plate and... well... put stuff in and squeeze it out at the same time. Another thing that should be addressed if you ask me...
