Travelling back from a meeting yesterday and waiting for the train (which, for some reason, you can never get reserved seating for)
I stood on the platform for a good 15 minutes, didn't sit down as I knew the train would be busy and wanted to get a seat. Train came and I made a move toward the door, the same time as another woman. She gave me a look and said "excuse me, but I've been waiting for half an hour for this train".
I'm not a fan of confrontation so I let her on. However, whilst she had been waiting longer, she'd been sitting in the waiting room on a nice comfy seat. I had been standing in the heat on the platform.
So who should get first dibs on the seat? The one who's been waiting longest, or the one who's put themselves out more?
