the robo issue is really an app issue. The question is how soon?
Mcdonald’s will soon have an I phone app that allows an order to be placed on the I phone and picked up at a dedicated drive in window. no money will change hands because the transaction will be conducted via a credit card or perhaps a Mcdonalds card.
The new Mcdonald’s already have two drive ups. Making one a dedicated purchase by ap window will not be a difficult transiton. When in the drive Q, the order number is punched in to the device and it is staged at the window for pick up
I already use Starbucks and Dunkin Donuts this way. I have phone apps with pre-loaded amounts and all they do is scan my phone to debit it. When the balance gets down to a certain amount, it reloads a small amount of money from my checking account. I almost never have to go to to ATM machine for cash anymore because coffee is about the only reason I would pay cash for anything.
A Wayback Burgers opened in it's place a few months ago. Most expensive burger place I've ever been to and not that good. Probably only had a third of the employees as the previous business.
Micky D’s was one of the first companies to accept ApplePay.
