I don't work in a kitchen but notice many people take it for granted. If someone is on crutches, people won't see the irony in saying "pick up that heavy object and put it in the oven". Hence all those old graphic kitchen accident commercials.
They're like stilts people with leg handicaps use to move around. You may have seen someone use them in school if they injure themselves. If you're using them, your hands aren't exactly free enough to toy around in a kitchen setting.
I know what crutches are and how they work, I've had to use them before.

This is what I'm confused about. Do you mean people would ask someone using crutches to put something heavy in an oven without taking into account they're using crutches?
