A 1957 documentary short explains how service stations work. We call them gas stations now, because no one is providing a service outside of taking your money and letting you use the toilet. But the video starts with a look at how you got gas for your car "a long time ago," which appears to be around 1890. I had to laugh at the station attendant checking the oil and showing the dipstick to the driver. The car is completely devoid of oil, but no one is panicking.
A film like this makes you think about how fractured our services are now. If you want a tire changed, you go to a tire place. If you need oil and lube, you go to an oil change place. If you have a different problem, you go to a mechanic shop. It's hard to get an appointment at any of those places, none of which sell gasoline. And if your car won't run, you must engage a third party wrecker service to deliver it.
A modern gas station won't even let you put air in your own tires for less than 50 cents, and even self window washing is disappearing, but they will sell you hot dogs, coffee, and all the Mountain Dew you can handle. And the restrooms are clean. (via Nag on the Lake)
