I suppose - but seems to me that McD's tend to reflect the neighborhoods they are located in.
The one I visit for my morning coffee is clean, offers free newspapers, and the help is courteous and accurate.
There is another one in a different direction, that I occasionally patronize. It is less clean. No newspapers, not even a box outside. The customers leave tables in a mess, and only napkins and salt and pepper are available for self-serve - if ketchup, plastic utensils, coffee creamers, jams etc. were left out, the customers would fill their pockets. Outside, take-out bags and wrappers pile up with the wind.
The workers are indifferent at best, and you better check your order. And they get mad while you do so. I never order fries there - workers, and the usual clientele both feeling there is no such thing as too much salt.
It could be that this particular McD's is like this one, and that their customers frequently try to rip them off.
