I was cycling to work this morning in light traffic and spotted 20 cents on the side of the road. I just kept on going.
There's a 5 cent piece at an intersection that I've been passing for days and I wouldn't bother stopping for it.
If I saw a dollar or two dollar coin I'd probably stop to grab it. If I spotted a note I'd certainly stop.
How much money would it take to stop you for a few seconds?
