I just call them not great developers. The users pay your fat salary and you yourself are a user for everything else in the world and at all other times. It's not some icky burden to talk to them or let them talk to you, it's the job. If you don't like the job, then you don't like the job, and should not be doing the job.

I don't have a lot of patience or sympathy for this attitude even though it's practically universal. There might be a few legitimate cases where someone basically has a handicap where they are clinically incapable, but then that's a handicap like a broken leg. A defect. Maybe it's ok to make allowances for them in the name of equality but it's absolutely making allowances, and should not be a norm and should not be something just everyone gets to claim for their mere comfort and convenience. IMO anyway if I were king and all that.
