Jolly Rancher, you left out those who come in quietly listen to what’s going on aroung them, take the drink/food-for-thought, respond politely to questions, and move on with their day. They know the owners, would recognize them if they saw them on the street, but the owners only know them when they come in and ask for their drink.
Great comparison! (Even though I’ve been to 7-11 only once in my life.)
