This sounds like something that happened to me at Burger King when I was working. A girl in drive-thru sneezed and I said "Bless You," and she said, "You can't bless me! You ain't MY God!" bahaha. People.
This is mean but I think everyone has at least one person in their life that if they caught fire it would take a minute or so to choose between a bucket of water or the bag of marshmallows. Or in my case choosing between water and a can of gasoline :)
