Irritating sign at the gym

This sign bugs me! It's one of several in the same venue and they all read the same. I would like to take a red pen and mark it like a teacher would!
Blustery day with hardly any rain so I got the washing dried.
Went to mum's and could not park on the street near her house or on her drive due to badly parked vehicles so had to park in another street. Selfish people. This is going to be an ongoing problem since the vehicles are always causing problems lately.
An irritating day at times!
