If there is no person going in or out of the building or does not carry any bag, the security just sits there doing nothing.
Three ladies are entering the building and a man is leaving the building at the same time.
The man stands aside to let the ladies have their bags checked first.
The security guard gets impatient and raise his voice, "Quickly come here. Don't waste my time."
After the guard has checked the man's bag, he sits down and continues staring into space.
