Best Low Volume Specialty/Fellowships?

What fields of medicine do you generally deal with lower volumes of patients in a day? ESsentially a field where you're paid to sit around and wait for patients to come in that generally produces low volume/waiting for consults.

I want a field of medicine where you paid to sit on your butt and not do anything while waiting for consults? also a field with alot of no shows potentially but im still getting paid by the hour? thanks
