Well if you follow the "cause and effect" saying, the patient ought to pay for it. But if you think about who took it of the shelves, the off duty officer and the two nurses ought to pay.

But if the manager is stupid enough not to see the value in this story as a commercial or word-of-mouth-extra-sale i think he ought to pay.

Still, you can compare the scenario with an officer borrowing a car from a civilian, in order to prevent a catastrophe. The civilian probably gets to pay for gas in the end.
