Apple employees keep crashing into the new HQ glass walls? https://www.engadget.com/2018/02/16/apple-employees-walking-into-glass-walls/
They always say that transparency is not good for all situations - I would say use stickers
It was true during the first two days of move in. The entire building is with glass wall, glass door. People were not familiar with the building. It is quite large. Facilities has added sticker dots on those glass walls now to provide some visual to identify them. Post-It Notes was used temporary as facilities added stickers dots.
Thats hilarious
