the older I get the less enamoured I am with buffets

I used to like the idea of getting to try small bits of things to see if I liked it. I was never after the all you can eat aspect. But now that I'm old, and I've seen a few Buffetts and worked one while in college at an old folks home, I can absolutely say, Eww. Too many people put food back because they didn't eat it all and don't want to waste it. They touch and handle things.. they poke at the food with their hands.It's bad enough when the food is already coming out of a kitchen which you are unaware of the cleanliness or the considerations of the cooks, but then to put it out for the general public, and their children, to handle without any assistance... eww.
Also, when a small child vomits next to the buffet, how far do you think the particles splatter?
