Missing a Toilet?

Couldn't pass up sharing this sign with you all. We spotted it on the way up for a "Family Adventure Afternoon" at Petrin Park. The text of the sign says something to the effect of "Service Vehicles Only", so nothing about toilets.

Looking a little closer at the sign, it looks more like someone decided to play a prank on us - the toilet stencil is cut out, and pasted onto the sign... it's not quite straight, and not quite centered - both dead giveaways when looking at signs for toilets!
