You got very drunk in a bar and didn't even know if you would make it home in such a state. And then the bartender offers you his help to take you home. His shift was coming to an end, so it didn't make him uncomfortable. You gave him your address and after a while you were on your way somewhere. You didn't even notice that you fell asleep. You don't wake up at home, tied to a radiator and sitting on the floor.
