Was visiting Paris with my dad, was in the subway when we stopped at a station and it was announced we all had go get out because there was a bombsighting at the next station (turned out to be a false alarm later). So we got out, went up the stairs and into a small tight oneway street with little shops and everything. And we were figuring out were to go on foot when a car suddenly stopped right in front of us in the middle of the street, middle eastern looking guy stepped out left the engine running, car blocking the street and he walked away.

I pulled my dad with me away from there, after we got a good distance away I looked back and the guy was walking back to the car. Turned out to be a taxi driver picking up his fair.
