Annoying things that happen on the tube

1) Someone getting to the gate and THEN looking for their Oyster card
2) Someone getting on a packed train when there's clearly no room then shouting "can you move down please"
3) When you have to get off the tube to let other people off and the people waiting on the platform then get on before you've got back on

MOAR? Observational comedy huh? Haha, brilliant.
