A recent McDonald’s visit left me scratching my head. An old geezer (I use the word advisedly) returned to the counter to return his sandwich because it had cheese on it. Since the sandwich comes with cheese normally, he would have needed to request it to be removed, which he had not done. I know this because he made his order loudly and I was standing behind him in line.
He used the occasion to argue just as loud as he had ordered.
