We use a sign like this all the time at work.
Caution. Cuidado.
Wet floor. Piso mojado.
As you can imagine at a restaurant there are quite a few spills.
The first thing we do is mop it up and then immediately throw down one of these yellow signs.
Every now and then you'll see one by the entryway.
This one was posted right outside our local grocery store.
The floor didn't seem particularly wet.
There were a few clouds in the sky though.
Is that enough for a wet floor sign? I don't know.
I thought it was perfect for Color Challenge Wednesday Yellow.
