John sells 2 types of coke - regular coke at $0.90 a cup and diet coke at $1 a cup. 2 customers came and each bought a cup of coke within 5 minutes of each other. Both asked for "1 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?

The second person may be FAT so he brought diet coke......

The second customer paid in change, some of which were monetary units less than a quarter.

Might be John is having just 1 regular coke which he knows first customer will buy as it is cheap and the second one has to buy diet coke

The second person paid $1 in change, like 10 dimes, so there would be no reason for them to include the tenth unless they intended to buy the diet.
