If you know your price is competitive then just tell them you can’t do the work to the best of your ability at that price. If you’re not overcharging, then just let that customer go. Those customers are a pain to deal with. If they don’t see the value in your work then just go on to the next job.
I like that advice it’ll be hard to tell one off unless your client list is full
You have to tell them to kick rocks. Because, you will have to deal with that person's energy until the job is done. And, they may decide not to pay.
My client list isn’t that long at all
