I long ago gave up on the drivethrough, but to me it seems like this set-up couldn't possibly make it any worse. It'd be nice to order from someone who spoke and understood English, but something tells me companies willing to outsource something as cheap as a minimum wage position are not going to have the most stringent hiring standards, whatever state they're in.
As for DIY ordering, I'd be a big proponent of it at most fast food joints. Granted, I once spent five minutes at a local WaWa (basically a 7-11) trying to figure out their ridiculously poorly designed touch-screen ordering system, but I have faith that someone like McDonald's would have the money to design a system that actually made sense. (I was trying to order a bacon/egg/cheese on a bagel--not brain surgery. Was it under breakfast? No. Bagels? No. I gave up and went to a deli down the street.)
I used to be terribly against the idea of those self-checkout lanes at supermarkets, but they converted me. Sure, the price of groceries hasn't dropped, and they probably put a high schooler or two out of a part time job, but them replacing two regular checkout lanes with six DIY express lanes means I spend a lot less time losing brain cells reading the front of the Enquirer.
