It wasn't big and it wasn't clever, but it was kind of satisfying
I recently had a nasty injury playing football. I had this big protective boot strapped around my leg and I was on crutches. For a few weeks I wasn’t really able to leave the house, but as things improved I was able to go back to work, which meant taking the train. Even on busy commuter trains people were generally really considerate when they saw me on the crutches. They would offer a seat, make sure I had plenty of space, give me time to get on/off at my own pace etc.
Not everyone though. One day I was getting off a busy train, the passengers about to get on were giving me time to get off. But there was one guy who didn’t have the patience and so charged forward to push me out the way. As I half fell to the side I just grabbed his arm to stop him getting on.
(Fake concerned voice) “Oh no I seem to be falling, let me grab your arm. Oh no I still need your arm in case I might fall. Oh no those people are getting on now instead of you. Oh no the doors are closing. Oh no the train is leaving. Oh no you’ve missed your train.”
He missed his train and I went off with a spring in my step for the first time in weeks!
