My Dad was so funny. He passed away last year, but the months prior to his passing he had to have his McDonald’s cheeseburger and a small fries for lunch. Not the big cheeseburger... the small one, kid’s meal size. He and his wife would get one each and a small fries. He loved getting his lunch for a couple of bucks. When I would take him to the doctor and try to swing by a BK on the way home, he would say.... no... go for the Mickey D.
My grandfather (RIP 1987) worshipped McD’s coffee. My mom (she adored him, so no disrespect) thinks it was mostly because he was cheap as an old man!
