I saw similar engraved and then inked onto wooden boards at a restaurant, sadly, despite the error handling, 3 out of 4 I tried were not scannable, the 1 I did manage to scan to me to a reviews site for the restaurant (where a lot of reviews said they struggled to make the QR work - likely not the feedback the restaurant wanted)! I guess it kept me entertained whilst waiting for the bill.

There was a tweet a while back where I guy was riding a train in China and took a photo of the QR code for his seat. He mentioned that you can use the QR code to order food and drinks delivered directly to you.

About 5 minutes later there was another tweet from him where:

- someone saw the original tweet (Guy 2)

- scanned the QR code

- ordered the OP a drink

- added a note to the order saying it was from Guy 2

Always loved this story.
