Just that really. I get the train to and from work every day and it's amazing how many times I have to ask someone 'Can I sit there?' after they've sat on the end seat or dumped their small bag next to them. I can understand if the train is empty but at packed rush hour?! Everyone ends up standing near the doors! Why does anyone have a right to take up two seats???!! Arghhh! (Can you tell I've just got off the train!;))
