In my place, after you order and pay, you're pretty much on your own for the rest. We do bring you your meal, though. And because of the lack of service we don't expect tips and all the locals know that.
I do have a kids menu with mini corn dogs, chicken rings, grilled cheese and even a childs portion of BBQ. Think is, I have a self service bar area for drinks, condiments and burger fixings. This also includes crackers for salads.
What I don't have is bus staff available and most everyone knows it. Most guests are good about throwing the disposable away IN the trash center provided and leaving the hard dishes ON the trash center for us to clean up. I run the register and clean tables between guests that come in.
I serve a lot of families and most are really great, but a few do not order their kids anything. Instead, they grab a handful of crackers and put them in front of the child, thus leaving the place in a mess knowing that we don't have the personel to clean it up right away.
Paul, I'm not talking about the everyday kid and the causual clean up associated with them. I used the term "saltine snowstorm" for a reason. You're argument, though, might be a great thread.
