I live in Brazil, we don't usually buy food at gas stations, as we don't generally leave the car when filling up the tank lol
but when I go buy myself some snacks, I usually get myself a big bag of cheetos, a couple of chocolate bars and some coke to drink (they usually don't have pepsi, but I always take pepsi if I have the chance lol), mostly because food is expensive and I don't have much money, so I just take the cheapest options, but I still like what I buy ! I'm content with it ! :3
