A few years ago, my father-in-law went to Canadian Tire to get his car’s flat tire patched. When he got it back, rim and all, he took a look and realized the guy – whose sole job it is to fix flats and put tires on rims – had put the tire on the wrong way. It was the end of the day, so my father-in-law just took the backwards tire, threw it in his trunk, and left. He’d deal with it another day.

That other day came.
