Changing oil at Jiffy Lube. It’s like the “McDonald’s” of the auto service market. They have 2000 locations in the US and 24 million customers annually. It looks like a gas station, just a bit slower.
You arrive at the location. Immediately, an employee runs up, takes your car keys, sends you to a cozy waiting room (11:50), and then sits in your car in line.
When it’s your turn, they open up the car (mine is in the background) and invite you to discuss the set of services (12:00). Typically, this includes an oil change, filters – oil and air, vacuuming, windshield wipers, antifreeze, brake fluid.
By 12:15, they return your keys and charge your card. Your car leaves, and a new one takes its place. A conveyor belt of services in action.
