The thing that stands out here is that some pilots seem to think they own the home airport they operate from!
No doubt they know the area well. Know all the frequencies and procedures. And read the local notams!
But that doesn't give them the right to be judge, jury and executioner!
It can be frustrating when someone supposedly gets it wrong and creates a problem. But the last thing they need is the current gods gift to aviation giving them a public dressing down.
Offer them help with their baggage. A lift into town perhaps. By then everyone has calmed down and you can chat about the local procedures.
Some pilot's feel under-confident and intimidated when going to unfamilar airports. Despite doing their homework, they still get things wrong!
We all need to be aware of that!
