My local chinese buffet restaurant charges $8.50 for every adult.
They have shrimp, lobster, salmon, and other products that when you go to the market and order a pound of shrimp it will cost you you around $7-$8

There are some fat people that eat a lot, some children that grab and grab and won't eat everything. I've even seen full plates being disposed.

My question is, hoiw do they make money?
Everytime I go to McDonald's or to a Tokyo Lunch Boxes & Catering place. I always pay more than what my stomach needs!!

I'm not fat and I eat like an average person my age and weight. But everytime I go to TokyoLunch Boxes & Catering I end up paying $60 for sushi and soup, and still feel like I haven't got enought, and with McDonald's is the same thing.

Could it be because Buffets serve us with low quality products?
Or could it be that because of their prices we are making franchises super-rich?
