Am I the only one bothered by a pet charge at RV parks?

Agree 100%. I have never been to an RV park or similar establishment where there was ever any dog poo left on the ground. Every RVer cleans up after their pets and they always have their own poo bags. Those same dogs are also always friendly, never bark, always stay in their own sites, so there is really no need for a leash. All pet rules and policies are actually ridiculous on face value. They are just another way the mean and greedy park owner gets into your business and wallet.
