So say that, hypothetically, there’s a sign in an office suite over the break room sink. It warns the lazy and slovenly employees that a hidden camera has been installed in the room, specifically to figure out who has not been washing their dishes, leaving them instead for others to scrub.
At the bottom of the hypothetical sign is a note intended to be clever and funny, informing people that in the time they “just spent looking for the camera” they could have washed their dishes.
It’s vaguely funny. This hypothetical sign, however, only has any impact in an office where the employees already assume that their managers would invade their privacy in such a cavalier fashion, and wouldn’t feel the first qualm about spying on their lunchtime habits.
