The Japanese restaurant we went to last week had an all-you-can-eat menu. It stated that the time limit was 90 minutes and urged people not to waste food. What a shame that some people are totally without moral compass.
I had Peruvian friends I'd go to a buffet with that served breakfast, lunch and dinner. We would have a late breakfast, sit around and BS, then eat lunch when it was brought out. I have no idea why the breakfast crowd was not kicked out before lunch was served. Always seemed like stealing to me.
I get monthly emails from our Dept of Wildlife Resources (game wardens) telling of some of their exploits. There was one where a father and son were in a store acting as though they were on drugs. Turns out they had those "special toads" at home they were licking. According to that email, the thin slime is a hallucinogenic, and just underneath is a toxin. I have no idea what tribe those guys were with.
