given how often disabled people are yelled at for using disabled parking spots, I would not be as optimistic that we’d not be included
As for how they were able to use it, maybe using it for a little bit is okay but it starts physically hurting after a while leading to them not being able to put it back, that has happened to me before. Or maybe the return cart area is a bit up a hill or otherwise inaccessible
its not that simple. pushing a full cart could start the pain at which point you’re just fucked, pushing the empty cart back might really just be too much after that
