Can't happen quickly enough for me.
When I go to a fast food establishment I require tasty food FAST. Should I have to wait in a queue formed because its employees can't get their act together, I will not only depart but I will likely never return to that establishment.
I would much rather go to a Robo-Burger franchise being able to immediately place and pay for my order and receiving it without human intervention.
Should McDonald's crack the code on this type of establishment it will make another fast food fortune.
As for the fast food "workers" protesting themselves out of jobs; "good luck with your welfare prospects."
Heck, you’re lucky if nowadays the person taking your order habla ingles.
