Yeah yer best off taking the "high road". Tough to do, very often. Last year while queued in traffic I asked a guy in a car to put his phone away (he was texting, not yacking on it). He started swearing at me and threatened to run me off the road.
I wanted to
but decided just to bugger off and get on with my day.
We all have stories like this, unfortunately, and usually quite a few stories each.
