Three guys go to a restaurant that says all the meals are $10 each, pay when you enter.
So they order, pay and eat, but at the end of the night one guy says:
“No way, that wasn’t worth $10 …. maybe $9 !! I’m going to complain!”
So he tells the manager who agrees initially -but then he says:
“We do not have any one dollar coins remaining, but do have a $5 note. Do you have a $2 coin?”
The three guys do, so they hand it over.
Who came out with more money, the three guys or the restaurant?
