What would you do?

So, this morning, I was doing my weekly run around town, doing errands, grocery shopping, etc.  As I was returning my shopping cart at the grocery store, I noticed someone had left their cart in the cart drop-off area, but had not retrieved the loonie in the slot.

My immediate thought....."score!"

I locked up my cart, and looking around to make sure there were no "Just for Gags" cameras around, I locked up the other cart and stuffed the loonie in my pocket. 

Finders keepers, losers weepers.

I sat in the van, thinking about what I had just done.  Something in me niggled.    Have you ever had a niggle?  If life has taught me anything, it's to listen to the niggle. No loonie is worth the cost of carrying around a niggle. So, I picked up the loonie (a shiny 2013 model!) and climbed out of the van, and stuck it back into the shopping cart.  By now, I was feeling a little stupid for unlocking a cart and purposely leaving it there, but whatever. No sooner had I climbed back into the van when I spotted another shopper approaching the cart dropoff.  Her eyes immediately caught sight of the loonie (I was parked a few feet from her, so I could watch her).  After a quick look to the left and right, she snatched that loonie faster than you can say "heywhereyagoinwiththat". I don't judge her.  Two minutes earlier, that was me.

It just makes me think.  Would it have been wrong to take the loonie?
