The US Energy Information Administration gives this answer for August 2022:

I was buying gas recently, and because I was also picking up snacks, I went into the gas station to pay the cashier rather than swiping my credit card at the pump. I said something low-key conversational about “price of gas sure is up” and he visibly winced. So I added something like: “Of course, the gas station makes, what, about 5 cents when you sell a gallon of gas?” He visibly relaxed and even gave me a rueful smile. It made me suspect that the customer service people behind the counter, everywhere, have probably been taking a lot of face-to-face direct heat for higher prices.
