Order EVERYTHING on the menu then when it arrives say you don't fancy any of it and just have a glass of water.
Follow the waiter/waitress. (Even into the kitchen.)
Order something thats not on the menu, then when told they don't cook it either cry like a baby or act like a snob shouting about how disgraceful the service is.
Eat food off other peoples tables. (Works well after they've left or if they're still eating.)
Try convince the waiter/waitress that your the queen of England(works best if your a boy) and claim that you don't have to pay for anything.
Dress like a tramp and sit in the exact middle of the restaraunt. (Even if the exact middle is a table.) [Works best if you actually use a tape measure to find the exact middle.]
Flirt with everyone you see. (No matter what gender.)
When they sere you food, demand to see themanager and when he comes and trys to calm you down, Shove food down his shirt and pants, and ask if it taste good to him.
At mcdonalds or some fast food place, order a hamburger or something like it, eat all of it exept like 2 bites, then demand a free meel cuz they got the order wrong, do this multiple times. :o
I dream of a better tomorrow, where chickens can cross the road and not be questioned about their motives.
