The sites were large sites.
When we dump our black tank we do not smell anything. You can not believe the stench this was when he rudely dumped his tanks during our dinner time with our friends there!
We were there for a couple of months so was not handy to go unhook and go to the dumping station. I guess this man decided to do his weekly dumping that day during our dinner.
As for the rude comment about not farting near us. That is not a problem. And if you can not see anything wrong with what this man did then you have no camping manners.
Or next time you see someone dumping next door to you........Run outside and eat your dinner.
