No, not what you’re thinking.
I sat down on the train on the way home and somehow the armrest slotted into my front pocket.
Annoyingly the distance between the seat, my bottom and the armrest was about an inch too far.
Riiiiip!
Embarrassing but worse, the material ripped rather than just the seam.
One pair of suit trousers ruined and one suit jacket now redundant.
