At the end of the semester, the guys living on that floor were billed for recharging the fire extinguisher. You see, the school had a written policy that if a fire extinguisher was discharged, and no one knew who did it, the recharge fee was spread across everyone on the floor.
The idea to give students a financial incentive to not discharge fire extingishers as a prank. There was no exception written into the rule for fire extinguishers actually used to put out fires, so, "rules are rules" they guys had to pay.
And they wonder why the alumni don't donate more to the school.
Some people just never seem to realize that the rules don’t always HAVE to be enforced.
Which is why, I suppose, those people are promoted to administrative positions.
