Yup... people not knowing how to operate the machine, not knowing what they want to drink, and just how much longer it takes overall can make it a little frustrating.
I have seen people pick the drink they want and then just sit there, long enough for the machine to go back to the main screen. I was sitting at the time but was watching them, they ended up going to the cashier and raising a fuss about the machine not working. If I was in line, I would have walked them through it, like I have many times before.. But I am not going to get up and interrupt my meal.
Or they would pick out what they want to drink, THEN get the ice, and by the time they want to pour the drink out it goes back to the main menu.
The freestyle machine is pretty nice, but for a Mcdonalds location they would need at least two, and I am sure it could get pretty expensive for them.
