Cute service in car gas station from Japan

Upon turning into a gas station in Japan, the customer's car is assaulted by attendants, checking the oil, consulting with the driver, checking the tires, and so on. A stark contrast from service in the States where the service is good if the cashier doesn't glare at you when you give him your money after pumping your own gas. After the car leaves comes the bow. I counted these three gas attendants bowing for 14 seconds towards their departing customer. Truth be told, it is unusual (even in Japan) for attendants to bow this long after a customer has left and already forgotten about his roadside assistants, but there is always a bow at the customer's departure.
