The kitchens at McDonalds are mishmasses of food everywhere: onion and mustard are in the catsup; both are in the mayonnaise. what you are served is a fair selection of whatever you have ordered plus whatever has been added on by carelessness-or pure sloppiness. I will eat certain breakfast items at McDonalds; I would go hungry rather than expose myself to any lunch or dinner there. This is not an opinion based on a single visit but on a number of visits over a number of decades in sites across the nation. Their advertising must first rate or they would have done under decades agfo.
