No, it was four years ago in 2012, I was surprised myself how long since I last visited.
Gas (petrol) always goes up there in the summer anyway but at that time everybody thought it was up to stay up. You have to pay the cashier first before you pump the gas and I was a bit miffed to find they charged the same for using a debit card as they did for a credit card.
Dang it, I can still remember paying 96 cents a gallon in Kansas in the 90’s.
