Two years ago, Sabrina Plannerer and her partner purchased a Shell gas station under construction in Brazil.
An adult dog was roaming around the area. He had been abandoned there by his former owner and was too frightened to leave.
The formerly frightened dog proved to be a natural at providing world-class customer service with a smile. Negão says hello to everyone while they fill their tanks and the customers love him. Some even bring him toys.
Once a day he is taken on a walk where he is an adorable advertisement for the station.
