These images are extremely funny and ironic at the same time. Nobody expected this when they gave this janitor the task to clean the snow from the front of the building and to make it a passing lane. But when they walked down the aisle they realized he was making fun of them!
He thought it would be a good idea to give them a little hassle and started to clean the driveway in zig zag. Some of the other employees have realized and went on their way, but most of them have struggled to maintain on the route created by the vengeful employee. Extremely funny!
