I picked up a nail in the Camry the other day so I ran to the local tire shop over lunch to have it plugged and I had this thought:

If I were a tire shop owner, every time I had someone come in with a nail/screw/etc., I’d take it out, plug the tire, then throw the nail in a coffee can and keep that can in my vehicle. Then as I’m driving around town I’d occasionally chuck one or two out the window and hopefully drum up some business.
