Have you ever gotten your dry cleaning back with a tag saying “We noticed a broken button on your shirt, so we replaced it for you free of charge.”? At first you may feel warm and fuzzy like your mom is taking care of the little things for you. But if you sit back and think about it, you would probably realize that the likelihood that you brought it to them broken is pretty slim, unless you are wrestling in your dress shirts.

Dry cleaners know that their machines will break buttons from time to time and rather than have you notice it and bring it back to be fixed, they check for broken buttons and replace them before you get it. What could have been a bug in their system is instead a feature. Do you have a bug you could turn into a feature?
