it's about reducing the labor force. States like Washington and California wanting/or have pushed minimum wage to 15 an hr, if they can perfect the mobile or kiosk ordering, they can reduce their labor costs by 75% or more and eliminate those jobs.
I get that, but really don't think they can reduce much more. They still need to cook it (or whatever the do to it. Lol) and hand it to you. They usually waiting a moment for the food after they are done at the register anyway.
