At least they will be less likely to play games with you.
I did just that. Even showed the scale guy that it broke while sheet bends. But they are good to me 99 percent of the time and these days I rarely scrap crutches or walkers so I am not too worried about it.
It's my personal policy to not argue with the small scale guy. If I had a whole load of something and was having an issue I would just go over his head or just take the material somewhere else.
