I would like a named list of such buyers. Not their employers. The actual natural person names. So I know which clients to decline outright based upon the name of the buyer I'm working with, if I find out they are anywhere in the chain of procurement during negotiations. I have happily told buyers "no" on numerous occasions (there is an art to how to decline a customer's request, or to decline the customer themselves). Warren Buffett was right: knowing when to judiciously say "yes" is a key factor in managing your time.
