Civic honesty around the globe

I found a wallet in a parking lot of a mall in Warsaw, Poland. The customer info desk would accept it, citing "internal regulations". Maybe I should just have dropped the wallet on their desk and run away :)

(Owner found me, because the info desk at least wrote down my number)

I'm guessing you meant "wouldn't"?

Nuremberg, Germany: I once found a wallet with most of the cash already gone, but loads of cards and ID cards in it, and other stuff, pretty thick. I went to the police - and they were not exactly happy. They would have preferred to send me elsewhere but admitted they were the only ones open at the time. I can understand why they felt that way - it took well over an hour, every single tiny item in the wallet had to be catalogued, an arduous procedure for sure.

How did you know "most of the cash [was] already gone"?

Yup, typo.
