Mike you asked some one who knows what they are talking about to jump in with an answer, so I did.
I
have gone out on their behalf and cleaned half finished carpets, customers
do claim against the hirer for damage
they have caused.
If you choose not to believe this then theres nothing I can do about that. :

I have qualified the answer with personal experience and my experience of dealing with claims on a large scale, you simply do not want to accept it because its me who's giving it, thats fine by me.
But if your going to answer everything I say with
'that's crap' at least try and have something useful to add after that backs
your claim to have knowledge on the subject, which you clearly don't.
enough said.
