The real reason
Those anticipating a refreshing swim in this pool would have likely been dismayed upon encountering this sign. However, owing to the error on the sign, the prohibition might not be such a disappointment after all.

The intended message on the sign is ‘Sorry for the inconvenience,’ but it mistakenly reads ‘incontinence,’ which is an entirely different matter. Perhaps incontinence is the genuine reason behind the pool closure, and they’ve summoned pool cleaners to address the issue in the water.
