Or get rid of all change! A while ago I read an article that proposed replacing change with a chance to get a dollar. So instead of 13 cents due to you: 1. you generate a random number from 1 to 100 2. if the number is <= 13, you get a dollar; otherwise you get nothing Over the long run you would have about the same amount of money. And you would have the added benefit of not having to deal with change. Coming up with a (verifiable) fair way to do (1) that is accessible to everyone is problematic though...
