I notice dogs frequently on airplanes now. They "ban" peanuts if someone claims to have an allergy, but I see 2-3 pooches on the plane routinely now.
And like HDCP parking spaces, folks found out how easy it is to get their dogs labeled as "service/support animals". I know a couple who did that so they could take their dog anywhere. He's a great dog, but I don't want him in the grocery store.
Humans will abuse any privilege given to the few for good reason. In not many years, the few become the many.
Most of the folks parking in HDCP spots at Wally World are, well, not thin.
