Ask HN: In 15 years, what will a gas station visit look like?

This struck me as an interesting sci-fi writing exercise. Gas stations are everywhere; but they'll likely change considerably going forward.

Imagine visiting a gas station in 2040:

• will it sell gas?

• what convenience items will it sell?

• who, if anyone, will staff it?

• what payment methods will it accept?

• what signage and decor will it use?

• will it offer new services?
