Basically I was that guy today, the bellend pressing the button to get off the tube.
If you have no clue right now what I am on about, the button on the door does not work it is automatic so you look somewhat of a dickhead furiously tapping it to get off the train early. NOTE: It does not help. It just makes you look like an erratic idiot with no patience whatsoever.
I blame it on being too tired, but still no excuse.
