Last time I went to McDonald’s ( many years ago ) you picked up your own napkins
"Life was simpler then. There wasn't all this concern about hy-giene! In my day, we didn't have Kleenex. When you turned seventeen, you were given the family handkerchief. ... It hadn't been washed in generations and it stood on its own ... filled with diseases and swarmin' with flies. ... If you tried to blow your nose, you'd get an infection and your head would swell up and turn green and children would burst into tears at the sight o' ya! And that's the way it was and we liked it! "
IF the man used the drive-up window, the staff puts the napkins into the bag.
He went through the drive-thru (I assume). Parking the car and walking his lazy butt into the store to get napkins out of the dispenser would have caused even more mental anguish.
That was a more civilized time when people took only what they planned to use.
These days people will grab 4 inches of napkins and 20 ketchup packets for their meal, use 2-3 of each and dump the rest in the trash, negating the profit margin for the meal they purchased.
