why shouldn't the customer be able to recover damages from you if you had an accident, or were negligent? they were paying you to take care of this stuff for them. if they wanted the risk of accident and incompetence, they'd just do it themselves.
Does that draw any distinction between paying and non-paying customers then as far as their rights? I see tons of "you assume all risks" sorts of Terms of Service, but I have a feeling those are likely just there and don't do much.
