I don't go to McDonald's that often, so I didn't notice the following happening gradually. About a year, maybe year and a half ago, I did notice a self-serve kiosk for the first time at a McDonald's on 23rd st here in NYC. At the time, it was optional to use or you could still place an order at the counter. Over the weekend, was out with my family and stopped in a McDonald's on 16th st in Chelsea. At that location, ordering by kiosk was mandatory. I stopped in another location just to see and it was mandatory there, too. From what I observed, the kiosks weren't that much more convenient. It took people forever to order, and some guy had to call one of the girls over from the counter to help him order
a coffee drink. It took the girl about 5 minutes to scroll through all of the menus for him to place the order he wanted. Then there was some sort of problem with the machine and he ended up leaving.

I stopped in a Wendy's about a week ago and I was surprised to see they had self-serve kiosks. It was after midnight and the kiosks were shut down for the night, which was strange because the place was so busy that people were leaving because it was taking so long to place orders.
Are self-serve kiosks already popular in other parts of the country, too?
