Greenman you are probably right, its just that I have never had the misfortune to have a relationship go that bad where I would severe ties. Sure, some have said colorful things directed my way, but again, I really don’t care. Pay me for my work and that is enough.
But I also agree with shoenista that I would not enable a client to endanger a different business relationship. I certainly have called some clients on the behalf of my preferred manufacturers to ask why their payment is past due and is there anything they can do to get that payment going.
