Most people don’t know how to replace a spare tire anyhow...how many people do you see stranded on the side of the road with a flat, calling AAA, even with a spare tire and tools in the trunk?
I was headed home one day and saw a gal stopped with a flat. She tried to call her husband and several friends, but had no luck. I told her I'd do it for her. I guess she trusted me since I was in uniform. Took me every bit of five or seven minutes.
