i really do not like when i order a hamburger with no ketchup and they still put it on . that 's the worst . i have that happen all the time but with onions . its the only thing they have to do so get it right ! i took one bite and thought i was going to be sick . did you have them get you a new one plus give you your money back for having to taste that nastiness ?
The food was poorly prepared or spoiled.
