Why Would a Professional Use a Waiver?

I would walk...99% of the time if you mention waiver the customer doesn't want to have it cleaned....but you get that 1% that say just DO IT IDON"T CARE.... so cover your butt and clean it..

but yes a properly worded waiver does work...that is my point

You can mark down on a waiver form whatever you want, don't take it to the bank.

Seen it far too many times Stanley.

Waiver is often not worth the paper its written on.

Small claims is small claims. Hard to predict what will happen there. You should know better than that.

You just got lucky. More power to you.
