"Kids eat free..."

Why do so may restaurants have the come on motto and advertisement, "kids eat free?"

Why do the airlines let kids fly free if they are small enough to sit on your lap?

Kids should be charged, double, triple, and quadruple. They take more time away from servers and flight attendants than adults, they constantly kick the seat in front of them, run wild on the airplanes and in restaurants, throw things, break thinks, and when they go to the restroom usually don't flush the toilet.

Why don't the restaurants let the adults eat free and charge kids double, triple, quadruple or even $4.00 per lb. This would cover all the broken dishes, clogged toilets and Valiums for the hired help.

I would frequent any establishment that would enact such a policy. Any takers?
