A long time ago, I was in a largish group of programmers, IT staff, and misc. staff which had been picked to participate in a mandatory daily meeting. It ran about an hour, sometimes longer. After a few weeks of this, one intern's phone began emitting a loud "BEEP" every so often. A few days later, the president was attending so the manager could show off. The intern's phone was beeping much more frequently, and the manager finally called on him. "Will you PLEASE turn off your phone!"
"Oh, sorry, that's an important meeting metric."
The manager inquired, "What metric‽”
"I calculated the total hourly rate of everyone in the room, and it beeps after every $1000. This meeting alone cost $5000 - so far! I could tell you the total from when the meeting first started, hang on..."
The meeting cancellation went out that afternoon. The intern also left, but he was graduating and already had a job lined up, so he didn't care.
