Not sure if this will catch on, but I sat down to eat lunch at a diner of sorts. In order to get food or drink I had to use the QR code in front of me to place the order, which isn't unusual. However, before any server spoke with me or had any staff interaction I had to pay for my meal AND leave a tip! 

Is this the new paradigm? 

BTW, I looked and did not see an option for no tip. I would've used that and left cash.
