Two weeks ago in Rio de Janeiro:
Took the airport bus to get to the hotel at Copacabana. Had my passport plus wallet in my laptop case that I did not want to take at first for the whole trip cause it should be leisure. Put the case in the bus bin above me. After 90 minutes drive in the too cold temperatured bus I saw my hotel, got out. Noted that I missed something...the laptop case.
Run as fast as I could and made the bus after 200 meters and got my stuff out. Otherwise I would have had big problems.
