It is unprofessional to cry at work.
Dave is a grocery store clerk who is restocking a shelf when he gets a text that his wife is dead, and he immediately has an urge to cry.
Dave wants to find a place to cry.
Dave sneaks outside by the loading dock at the back of the store and finds a place between two parked semi trucks to cry in private.
Dave gets up from the floor where he was stocking and wanders into the cashier area where he begins to bawl his eyes out.
The customers go on shopping without any clue that there is a man outside whose life has been torn to pieces.
The customers all feel pity on Dave and are saddened by his public display of sorrow and start to cry too.
