I would have given this 5 stars, but it loses a star because of an issue with the gas pumps. I had paid at the pump and selected the least expensive gas, but as I was going to begin fuelling, I noticed that the pump was showing the most expensive gas.
So I had to cancel the transaction and start again. Fortunately, I had chosen to print a receipt to make sure I wasn't charged, and I also saw that it had selected the expensive gas. But because I had not begun fuelling, my charge was $0.00.

Then I started again and made sure to select the least expensive gas as soon as the card went through, and I repeatedly pressed the button until I could see that the pump was showing that least expensive gas. When I finished, the receipt showed that it was the correct type of gas (least expensive) for which I was charged. It's important to always make sure the pump uses the type of gas you actually selected so that you are not unexpectedly overcharged.

I know that I pressed the correct, least expensive gas option the first time, and I don't know why the pump switched to the expensive type. I'm glad I was paying attention and caught it before I was over charged.

Other than that, this seems like a good gas station, with many pumps, and a carwash. There seems to be adequate space for cars to maneuver safely which is very important.
