An acquaintance had late stage cancer. Her family had been wealthy (her grandfather actually built and sat on the board of the hospital she was going to) but that was past. The cancer made it very difficult for her to earn money, and she fell way behind on her bills. A lawyer friend came to town to review the bills with the hospital and work out an arrangement.
As they were going through the bills, the lawyer noticed that every one of them had a $175 charge with no label. He asked what it was, and after some digging the administrator found out.
It was what they charged every time they weighed her.
