Here are a few random photos I had lying around from our lovely office.
Here's the coffee machine.
The photo doesn't really do justice to how very, very bright red this instruction is. This machine doesn't ask you to add more water, it demands it!
This is a light switch! The notice is probably there because the light switch is right beside the door, while the door release switch is 'round the corner near nothing in particular.
How rude! I think that this was a relic from the building work, and is now gone.
