Automation has been in use in Europe for years...long before our debate about $15 hr...never been able to figure out why they get tech long before we do.
They were using card chips long before us also...in a completely different way...waiter comes to table with wireless scanner, scans card and immediately hands it back...completely opposite of our use of the chip, where we put card in, complete transaction , take card out. Leave it up to us to screw that up too.
Back to the point - lol - at McD's across euro, enter order at kiosk, get receipt number, pick up at counter. Talk about efficient. Hey, did I mention how much better euro Big Macs taste than ours? Ok, I guess I've digressed enough :)
