Awkward Work Situation # 287

The restroom stalls in the first floor bathroom at work are kind of narrow. I always go in the slightly larger one because I don't want to accidentally touch the wall with any part of my body. So, one day a couple of weeks ago I was in the restroom and walked in to the slightly larger stall. Then someone else walked in and had to take the smaller stall (there are only two stalls). I guess this person was a bit larger than I am (or very very active) because they seemed to be having an inordinate amount of trouble with the amount of space allotted. There was quite a bit of violent thrashing and banging and they must have bumped into every single possible inch of all of the walls in that stall. They were knocking into things with so much force that I thought the wall between us was in danger of falling down. I didn't know what to do. I was petrified. Should I have offered to trade stalls with them? Not acknowledge the amount of trouble they seemed to be having? Offer assistance (ew)? I could not, er, perform under such pressure so I just umm stood there for a moment in disbelief and then washed my hands and hi-tailed it out of there. I never saw who it was but wow, I hope they made it out alive.
