As a former Hemodialysis Technician, I can tell you, those old coots get angry REAL quick. They're usually miserable pricks, which I can understand, spending 3 days a week, 4 hours or more a day, and a dialysis center is a pain in the ass. I think it's funny that the one dude was already in his chair, and hooked to a machine, that's about as vulnerable a person can get, you dont want to have your lines pop out, or you can legit bleed out.
Unfortunately though, the margin they have to overcome is only 5 games in 54, which isn't that difficult. For historical reference, the Celtics came from 5 down with 8 to play in '92 to win the Atlantic Division from the Knicks.
