The last Chinese buffet I was at, they had a huge pile of green beans on one of the random tables in the customer area and two little kids were snapping them. I don't feel like that's abnormal, but maybe I've just had interesting experiences.
I just envision you making those poor pimply faced minimum wage employees clean to an unreasonable degree.
Also, comparing a Buffet to a regular chinese restaurant is in no way fair. All buffets are disgusting.
