Found it. Since the gas goes through the same hose as the other blends, if you’re buying gas you need to get at least 4 gallons so the previous gas flushes out what was left in the hose from the previous sale, and fills enough of the container that the blend is primarily what you selected.
If you buy E15 and fill your tanks, then the next guy buys E10 and only gets 1 gallon, they might end up with a higher ethanol mix than intended, and if they use that on a small motor, like a chainsaw, it could ruin the seals.
Multiple tanks hooked up to one valve and hose vs. multiple tanks with their own separate valves and hoses.
Obviously, it’s a different kind of valve in the first setup to prevent backflow into other lines, but that’s probably about the extent of it. With the second setup, you probably need to run a new line and pump for each station for each gas type, compared to just tying the tanks into the one valve and pump per station.
I’m not a plumber or anything, though, so take it with a grain of salt.
Every fuel has its own hose and “pistol”. Each “pump” has two or three or four hoses.
While those do exist in the States too, a single hose and “pistol” is used for all grades of gasoline and the operator presses a button to select their grade of fuel. The only time there is a guaranteed separate is between desil and gasoline:
The button leads to some interesting minor social problems. The expectation is that the use uses their hand or fingers to press the button, but the buttons are usually disgustingly dirty, so that lead many to using the tip of the “pistol” to smack the grade of gasoline which may put a drop or two of gasoline on the button. So those that come next and use their hands end up smelling like gasoline.
No longer interacting with public gas pumps is one minor joy of driving an EV.
i’m gonna be real with you buddy i have never seen a “disgustingly dirty” fuel button so I think the people in your area just grody. no offense to present company.

I’m in Europe and I have never in my life seen a gas station that dispenses every fuel through just one hose.

In America, if a corner exists a company will cut it.
It feels like blending hoses would be a more complicated setup?

I feel like we should specific for Europeans or whomever that there is definitely a different hose for Diesel

I’m not from the US so my biggest surprise here is that you don’t get separate hoses for each grade.
Imagine getting Diesel in Germany. “Sorry, that was actually 15 liters of regular gas. ¯_(ツ)_/¯”
Edit: Ok, it’s not as bad as I imagined, since this picture seems to be about E15/E10, not diesel/regular.
diesel absolutely DOES get a separate hose, every time
