There is one, in fact there are a number of them… “working???” on the class.
I say that with the upmost sarcasm. They are doing nothing but touching numbers to act like they are actually doing work. Reminds me of my job doing stuff in the wafer manufacturing lab.
The amount of people that were able to get away playing video games or watching videos, in a sterile clean room, was actually hilarious. Just do the bare minimum to pretend to work, and no one questions the ethic.
