Pretty soon fast food outlets will have self serve checkout.

True. And that's not the only fast food trend that is easily spotted. McDonald's just tore down a perfectly good building near me to allow the addition of a new one with a super-small seating area plus a Drive-Through. Most days at the busy time there are 10 or more cars lined up and no place to sit inside.

Not for me. Off to Del Taco I go.

Most McDonalds do about 75% of their business at the drive through.
