I don't frequent Green Valley Grocery / Shell Gas Station all that much. I have stopped here in the past, as it is on my way to my old gym. It's all about convenience for me at gas stations / mini marts. The times that I have come here I have paid at the pump. And, I think that I have entered the store part once or twice for road-trip goodies or ice.
My reason for coming today was to gas up my fathers car that he let me borrow. Gas seems to be a little more expensive than the place I usually go to. $3.74 a gallon. But, what is $.30 cents or so more for a tank of gas? Like I said, it's all about convenience.
So, as gas stations go... this place is good.
