When you are dealing with a client and you suddenly see red flags (complaining about price, wants to micro-manage, etc.), how do you tactfully say "no?" I don't feel comfortable in lying and saying I can't because of a made-up reason. I need to know how to say I won't, in a professional way of course. Do you have a generic "canned" response? Or, do you give details why you won't take on their request?
