There is a Vietnamese restaurant here in London where waiters have QR-codes in the back of their tees. Just last week I was there and some older guy was following a cute tall and slim waitress around with his iphone, trying to scan it. Creepy as fuck, but I guess it was justified by the QR code placement.
