In 2006, I spent some time in the hospital after a bike accident. Someone who shared my recovery room was an guy with kidney failure & an extremely poor attitude. I learned he was running out of places to get dialysis because he kept treating the staff poorly & getting kicked out of the dialysis centers. Imagine having some poor newly hired receptionist trying to help this near death, abusive asshole & reading a note in the computer screen that said “do not treat this person under any circumstances”.
