Sitting on bench on station platform. Have carefully placed full cup of coffee beside me. Train comes in. Lady beside me gets up, and as she does so her shoulder bag swings and hits my coffee, terminally. She's very apologetic and offers to get me another on the train. I'm very annoyed but say no, they only do nasty coffee on trains, it's fine, these things happen. She insists and says she'll bring me a coffee and asks for my carriage number, which I tell her.
Now I'm feeling bad because she was so nice about it and perhaps it was my fault for putting it down on the bench. Am I a snarky twat or does she owe me a coffee?
