ER

Poor people couldn’t afford to go to their family doctor for minor issues, so they went to the Emergency Room at the county hospital.
Then, they ignored the bill from the hospital.
The county funded a set of neighborhood clinics to deal with this problem, but people kept going to the ER.
So, the county stationed a guy with a sledgehammer at the door, and he only let real emergencies in.
“Doesn’t the Hippocratic Oath say that doctors can’t do harm?” complained a social activist.
“I’m not a doctor,” the sledgehammer-guy said.
And he brained the activist with his hammer.
