The building where I work is in an area of new development and Amazon are our neighbours. A lot of the buildings in the area are unfinished but they’re slowly becoming populated; People appeared next door a few weeks ago and they started writing a message in Post-It notes.

Not to be outdone, I decided that Post-Its weren’t a reasonable response from a tech company. Enter the giant QR code.

This QR code points to BigDoor’s website and it works pretty well. I hope the QR code is the reason for the truncation of “are” and the addition of “hi!” in their message; there’s always the possibility they happen to be talking to the floor above.
