long before we were swamped in the myriad regulations and restrictions which hobble us today,
We did it to ourselves Gipsy. In long gone times, a person who experienced a bump and a bruise weren't out to sue everyone. We have evolved a "how could that have been allowed to happen?" society, which is okay, unless you want to go flying in "that could happen" airplanes with the "how could that be allowed to happen?" attitude. A extra detailed briefing will remind passengers that it could happen, and this is what you should do to make it least bad. If you don't feel you can do that, don't board. But, the passenger to be has to understand - detailed briefing!
