A good friend went with his buddy to São Paulo couple of decades ago, as part of a multi-country holiday trip.

As they got out of the taxi in front of the hotel, someone got shot further down that same street. They checked in, and went for some food. When they got back they learned the people in the room next door had just gotten all their stuff stolen.

They left right away after that.

Sure this isn't a unique experience, but coming from Norway it was pretty far from what we're used to.
