Just looking at the wall behind the counter in 7-11 boggles my mind. Dozens of cigarette and dip brands (and now vape and nicotine pouches too), with most smokers having a preferred brand and style - they don’t buy anything except the one type they like. Which means the demand must be high enough for each of those products to justify keeping them fully stocked all the time. Then consider that every corner gas station and convenience store has the same set up, even if they’re all within walking distance from each other.

That’s a lot of tobacco/nicotine users.
