After the Meal

Would it make sense to drastically reduce the "cleanup" time after humans eat their meals? I realize that at the dawn of civilization, tidying up after gnawing raw animals was quite a bit simpler. Then, as our taste buds became more refined and dinner was elevated to an art form, obviously there were more dirty dishes and silverware to wash. "Hey, you did this to yourselves," you could say. And you'd be right.

People in the new world are going to follow the same path -- you know it and I know it. So why not give them a dazzling display of your mercy and allow the grime to vaporize once the head of household gives a signal that the meal is over? Let me suggest three loud taps on the table with an elbow. This would give you both a visual and audible clue (in case you're multitasking).
