Will be great to see the OP jump back in...will go a long way to show that the post really was a genuine thought he had as opposed to stirring the pot and staning back to watch!

I found this to be interesting. It's something you wouldn't "think" should be a rule. But we also shouldn't need to put "contents may be hot" on coffee cups. Sometimes the obvious needs to be stated.

Here is something that's pretty simple to address. If someone points out information that's incorrect, you can correct it. And it's possible to do it while being nice. Generally if you don't include "you're a a$$hat" as part of that correction, it will actually come off as nice.

I think the whole point is reminding people to be people and show common courtesy. And it's by far a small minority. But unfortunately that minority makes up the majority of the noise. A busy gas station with hundreds of vehicles passing through every hour only needs one guy to flick a cigarette butt....
