Breathe over the water instead
Even baby turtles know not to breathe underwater. Anyone who can read this sign is definitely not a baby turtle. In fact, anyone who can read this sign probably already knows that you can’t breathe underwater. We say “probably” because there’s no ceiling on stupidity.
There’s no way to know what took place before management felt the need for this sign. So, we’ll come up with our own backstory. Someone got a back-alley surgery to replace their lungs with gills. They tried breathing underwater and nearly drowned. We’re guessing it was the same person who got his pinky stuck in a Chipotle wall.
