Coke Wars

John sells two types of coke – regular coke at $0.90 a cup and diet coke at $1 a cup. Two customers came and each bought a cup of coke within 5 minutes of each other. Both asked for “One cup of coke, please” and both gave $1 to John.
After receiving the money, John had to ask the first customer what type of coke he wanted but he instantly knew that the second customer wanted diet coke. How did he know?

  Because he paid in change, instead of a bill.

  Correct, Eric.

  The second customer paid in change. If he wanted a regular coke, he could have given .90 but he gave the extra dime because he wanted the diet coke.

  You are today’s winner.
