I really can't see what all the fuss is about.
If an instructor told me that I wasn't safe, I would listen to what he was saying - regardless of whether I thought he was legally in a position to refuse to sign my paperwork, this guy is concerned for my safety, and I want to know what he's concerned about so I can put it right. Once the problem is sorted out, I'll start worrying about the paperwork.
