after i quit smoking, my convenience store trips dropped by like 99%. it was one of those changes i didn't notice happening until i was across the street from the one by my house i used to hit all the time, and realized it had been completely remodeled. like a "huh, when did that happen" thing. when i shifted to remote/hybrid work, my driving dropped radically too. all i noticed was i was hardly putting any miles on my car anymore, but again.... my trips even to get gas at a c-store were now marked by the passage of months rather than "every week or so". and since i started limited my snackiness and drinking of nonsense, i have no reason to go inside anymore.
the markup on those places is insane. their value proposition is their location making them the only option for people living in a mutilated community and for people passing through with an impulse, and if you're not going in for tobacco you can probably get what you're looking for at those chain joints like Walgreens or CVS... also marked up, but usually not by as much. it feels like with the decline of tobacco and utter dominance of pharma in peoples lives, those places are taking over. it's no longer "ill pick up some cereal and snacks when i get smokes".... it's "i'll pick up some cereal and snacks when i get my pills."
