I got a ride from a courier who was driving as if the van was on fire. He looked at his watch and said "lunch time!". Then he held the steering wheel with his knee, and grabbed a 'Hoegaarden Wit" (beer) from behind his chair. Opened it with the bottom of his lighter and drank the whole bottle in one go. Did not blink an eye, grabbed another from behind the chair and repeated the process. Then only said "So !" and acted like it was perfectly normal. I jumped out when he halted at a traffic light. Looked back but It was an un-marked white van otherwise i'd happily reported him to police and his boss.
