Below is a quick photo while walking through downtown Munich one weekend.
Someone has books they'd like to sell. But of course there are few "garages" (it's all apartments, maybe with a large underground garage), and he/she probably didn't want to sit around all day for such a small volume.
So... why not simply set out the boxes of books, sign the prices, and leave a small piggybank for the proceeds?
Then come back at the end of the day, bring the remainder (plus money) back upstairs! (Cute piggybank, huh?)
The sign says: "Each book... into the little pig... thanks!" (left are 50 cents, right are 1 euro).
We're continually impressed with the behaviour standards in Germany when it comes to "trust" things like this.
It can be nice to live in such a law-abiding place - would this ever happen in the U.S.?
