I just improv, and be friendly. Everyone’s different.
If I were to hire someone to knock on doors, or talk to storefront owners, I would have them watch the program for a week or so, while having them wet, or even squeegee for a bit to get a feel for it before they try selling something they have no clue about. My marketing brain would say to hire your local super-extrovert university recent graduate lady to hit homes, and a hard-seller jock type for storefronts and keep it on commission. I’ve already done a little of that, and see where it works and doesn’t.
