Moments ago, I stepped out to return an empty 12-pack of beer. No less than four of my neighbours stepped out the door at the same time to do the same thing. The dépanneur clerk was a bit dazed.
When my turn came, I handed over the 12-pack and a snack cake and got back 50 cents. Drinking beer might not actually save me money, but it supports my brownie habit since I'd drink beer even if I didn't eat the brownies, but I wouldn't pay for the brownies. Works out well. :-)
