Nope. I talked to the individual within the company who would be my customer (and who realized that the type of insurance was unnecessary), and he knocked some sense into the purchasing people.
I’d given them a fair price (without including any unnecessary insurance) and had they held firm I would have walked away rather than charitably fund their operations for them.
What just slayed me though, was that they thought there was a difference between “them paying” for my insurance and “me paying” for it.
Glad to hear it worked out.
