"One guy when he needs to think or to take a break from his desk will walk around the halls pretending to smoke a cigarette. He will pretend to take a drag, pretend to blow it out, and occasionally tap the ashes. When he gets back to his office he will throw it on the ground and put it out with his foot. All imaginary. I asked coworkers about this. I assumed maybe he smoked and this was some way to cope with the loss of the ritual/routine but no. He has never smoked a day in his life."
