I once ordered a steak cooked rare. When the waitress set the plate in front of me, the steak jumped off the plate and ran back into the kitchen......
Roach on its back all 6 legs up in the air on top of my pork fried rice. No extra charge for the meat. :-)
I ordered a fried chicken at a fancy restaurant hotel. As soon as I cut into it, it started spurting blood. I lost my appetite. The maitre’d went back into the kitchen and FIRED the chef on the spot. For the next 10 minutes, all you could hear was shouting and utensils/plates, etc. being thrown about.
