Was at a bar with one of my mates and we met another group of guys who were good fun so we had a load of drinks with them. They had been drinking a lot as had we and they said we should all go back to their house for more drinks. We bought a load of drinks at an off-licence and then got in their car - the guy who was driving had been drinking. Fortunately half-way there I was like to my mate "We need to get out of this car and go home" so when they pulled over at one point, we got out and legged it.
We had no idea who these people were and it struck me when we were in the car that they were a bit dodgy... Fortunately we got out okay.
