I saw the funniest thing last night. I was on the last train back home and just as we were pulling out of Staines station, this guy in a suit bursts out of the 1st class compartment and starts trying to open the doors. When he realises that they won't open, he clearly loses it (maybe he's a ninja?) and starts banging the doors and then sullenly goes back into 1st class and starts punching and kicking the furniture in there too.
Now personally, if I'm on the last train home I'd have made sure I was paying attention to where the train was so I didn't miss my stop.
