I have to wonder if there's something regional to this.

I used to live in a walkable neighborhood in a southern city, and I had several workers and owners at the businesses on my block who were chatty and we got along well. I tipped a dollar for my coffee every time at a local cafe, and the baristas would give me free coffees or ring up my coffee as a refill. The staff and several customers would often get into chats and I made a few friends just from going to that cafe in the afternoons a few weekdays a week.
