not on my phone. I've tried because folks tell me to do it that way. Sometimes when the concession staff insist that's how it works, I try again with their help and they watch as it fails.
Do you still take rolls of quarters for toll roads?
I've recently been to a couple of bars outside - Barrel and Bushel in Tysons, and the Caboose in Mosaic District - and they both employ the QR code to order from your table. It works great once you complete the first order, and really expedites service. You click a couple of times and it seems within a minute or two the beer appears, paid for including tip. No more dealing with splitting checks, each orders and pays for their own. Unless your phone can't do that, of course.
