Usually a long line of random foods that will make you want to taste everything. This will result in a very big stomach ache and/or the inability to stand up and walk around.
Maria: Man! Look at this buffet! There's so much food! I'll just taste a bit of everything.
Bob: Yeah, right! I bet you five bucks you'll need help getting out of your seat after you finish eating.
(Later)
Maria: Here's the five bucks, now can you help me?
Bob: Nope. (runs off with money)
