When you go to Disneyland you are lucky to interact with maybe two or three speaking characters per visit, but you interact with dozens and dozens of CM's as they load boats, sell churros, ask how many, tell you to stay to your right, sell you a t-shirt, take your picture at the turnstile, etc.
I don't live on Main Street USA. I am a visitor at Disneyland. I don't know anyone who lives on Main Street USA, and when they sell me a Starbucks or a sweatshirt, they are not my "friend", they are sales staff serving me as a customer.
You actually believed Bob Chapek when he told us every CM in Star Wars Land was going to have their own backstory to pull us into their immersive world, didn't you?
