I believe OP made a well-intentioned comment in an attempt to prevent the camper from hurting himself or others.

When the comment was blown off, he offered one more polite warning.

When that was also ignored, the OP was courteous and shut his pie hole, as each of us would likely do ;)

Sounds to me like he handled the encounter with courtesy and respect.

I've jumped in and helped a family struggling with their popup roof without being asked (they had a young child trying to hold a corner of a failed lift mechanism). I got a big smile and nod. If not, I would have politely waved and headed back to my own site.

Watch out for your neighbor, offer assistance when you can, and wish them well if they prefer to handle it themselves. Camper's Code.

While I think his intentions were well-intended and his attitude as described was polite, I just don't think it warranted the intrusion in the first place. It wasn't an offer to assist the person, it was a comment on how he was doing was wrong.

Had the OP gone over with his rinsing hose and said "hey, I see you're using your fresh water hose to rinse out your stinky slinky. Why don't you use this one? I keep it just for that purpose. That way you won't contaminate your fresh water hose", then I would say he was offering assistance. But just telling someone "you're doing that wrong" is not assisting and tends to result in a negative response.

Again, I don't think the OP meant anything rude, but the old saying "the road to Hell is paved in good intentions" really fits. Regardless of what your intention is, unsolicited advice is rarely appreciated. Unsolicited help is more likely to get a nod of thanks.
