I am a freelancer and recently one of my clients was pinging me day and night about a particular project. He dug out EVERY little detail of the project and pinged me a lot of times whether I could handle something like that or not.
So is there any polite way to close the conversation or to just simply convey the message-'Take it or leave it?' without offending the client?
P.S. I can only hope he doesn't see this message.
