Thanks, Captain Obvious
We’ve all seen those “Do not use the elevator in case of fire” signs before, and we’re all aware of the idea: It’s safer to take the stairs while a fire rages through the building. However, this graffiti artist decided to push things further when they wrote “Use water” below the sign.

This sign was, without a doubt, self-explanatory. We didn’t need any further explanation for this sign. However, this individual felt the urge to make it abundantly clear that an elevator would not be able to put out a fire. If they were genuinely helpful, the graffiti artist might have added how useful a fire extinguisher is.
