Fuck me are you dense. Let’s walk through it, yea?

Normally all the prices are displayed, above each type/grade of fuel.

Once you select which fuel you want, that price remains and the rest go blank.

I had already selected a different fuel than diesel, and was pumping, so the diesel price had gone blank.

I took a picture of my little mischief here, the sticker, while I was pumping, and the diesel pro was blank.

After I shared the picture that I took while I was pumping and the diesel price was blank, it occurred to me that people might be interested in the local price of diesel fuel l.

Since I was currently pumping and the price of diesel was blank when I took the picture that I ended up sharing and realized people might want to know the price of diesel, I shared the price of diesel that was blank while I was pumping a different fuel and happened to take this picture.

If you need me to explain it differently, I can make an attempt.
