Works for me
I go to McDonald's solely because they have a *working* self-order screen. (as opposed to the useless broken shit at places like Wendy's)
Finally I can order without explaining it 4 times to someone that doesn't speak English as a first language and still getting it wrong 50% of the time. (Not that there's anything wrong with that, but a language barrier when I've got to get something to eat is not welcome... the language barrier is partly my fault as well, due to my rough Southern accent)
I certainly don't go there for the food, but they've got my business because of the technology.
