I’m waiting for a plane: it’s delayed already by 2 hours and probably will be later than that. It lands tomorrow morning in London and I have to go straight to work. I paid for business class because I had to work next day, but they’ve bumped me down to economy as they’ve screwed up somewhere. If I’m lucky I’ll get an hour or two of sleep. I really have to be at work tomorrow: any advice on getting me through, other than intravenous caffeine? Help!
