Seems like an especially good rule when working on planes or people. Now where did the surgical sponge go...
"No I totally got all the sponges out of the patient! How dare you question my authority!"
One is hand sanitizer dispensers that counts people entering rooms and beeps until all have used the machine, or even until all people already in the room have used it.
It's notoriously hard to get people to use hand sanitizers.
The other is convenient and fast dispensers that counts tools and sponges as they are used.
... and reliable. Not like those stupid vending machines. You would think after so many deaths they would have fixed the problem.
