By any chance..

His dog is big, white and ugly.
He reaches into his pocket and throws the piece of bread on the floor for his dog to eat. He speaks with the dog, asks if the bread was nice. Then he walks around, asking people who stand waiting for the train if they were smokers, he asks me: "Are you a smoker, by any chance?" and then: "Can you read the board, when will the next train arrive?" I couldn't see it either, so he swears and jumps down onto the rails. He bends down, picks up something and quickly climbs up on the platform again and I can see he has picked up a cigarette which must have been laying between the rails. He smokes and waits, and swears aggressively, he's fed up with waiting, he's fed up with all those people joining us and filling up the platform, filling up the train. The train arrives, he gets in and suddenly his voice changes to a smooth, warm and friendly tone as he's making his speech asking for money, while his dog silently follows him.
