Sounds like the guy needs a friend more than he needs a job.
He has friends. Read the post again.
He may simply be describing the two people that would actually notice if he vanished from the face of the planet as his friends because that is the closest thing he has to one.
It's fine to wash dishes if you need money, but if he ever wants a better life for himself, putting up with the annoyances of people who are not like you is a skill that must be both learned and practiced. Introverts, especially extreme loner hermits, have to sacrifice some of their essential spiritual essence to the vampiric extroverts occasionally, in order to have a better quality of being left the hell alone the rest of the time.
A guy like this really needs a mediator to introduce him to more outgoing types, let them have a taste, and then protect him before they scare him back into the shell. It's very unlikely he could do it alone.
