12 yr old McDonalds burger

A law firm I used to work for had a case involving a San Bernardino hotel's restaurant where a customer (the client) ordered a burger that was delivered to the table with a mouse's leg embedded into the meat. The day I started working there the office manager took me into the kitchen area, opened the freezer, then unwrapped and displayed the burger as she did with all new employees. "This is evidence in one of our cases. No matter how hungry you get, don't eat it!!!" You could see the little foot sticking out the side, perfectly preserved in frozen wonderland for God knows how long. Needless to say, I didn't eat at the hotel restaurant after that.
