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.
