Even though it's never presented locally, with that card cashiers would often get the "sign or pin" prompt on the terminal, and then ask me (or gesture if their English wasn't great), and I'd usually pick pin, which would then produce a slip with "No signature required" printed, which they would then insist I sign.
Just in the last few months I've noticed more contactless terminals at larger stores (particularly the nation-wide chains) but I can't imagine what confusing unnecessary process they'll end up using for that...
