I'd Like Standard Gasoline, Please

I was in San Francisco yesterday to have dinner with a friend, but decided to gas up my car beforehand. I stopped at this Chevron station on Van Ness:

But is it a Chevron station? Or something else?

The answer goes back to the Standard Oil trust that was broken up nearly a hundred years ago. Standard Oil was broken up into a number of different companies, each of which received the right to use the "Standard" name in a select number of states. But when one of these companies expand into a state where it didn't have the rights to the "Standard" name, they had to use a different name. Eventually it would drop the "Standard" name entirely, so that it would have the same name nationwide. This is how Standard Oil of California became Chevron.

Chevron still has the right to the "Standard" name in fourteen states, including California. But in order to keep the trademark rights, they need to actually use the name somewhere in each state where they have the right to. So in each of these fourteen states, there is one station, owned by Chevron, that uses the "Standard" name. In California, this station is at 1501 Van Ness Ave. in San Francisco. This station uses the "Standard" name on the exterior signs, but there are Chevron signs as well. Apparently ten years ago this station went as far as to use the "Standard" name on receipts, but the receipt I got yesterday used "Chevron".
