In Need of Extra Guidance
Many public signs are pretty straightforward. However, some do leave a little room for interpretation. Take this sign, for example; it clearly says that if there is a fire, don’t use the elevator. It was straightforward enough, but this cheeky artist decided to add a little extra instruction for those who needed it.

Nobody should try putting out a fire with an elevator, of course. However, if you need extra guidance, you should use water. Thanks for the additional information, whoever decided to give it to us!
