When people park on the street its often the case that you have to manouvere against the direction of traffic to achieve your end,its even a part of the U.K. driving test for gods sake.
So its no different for a parking lot.
So all the mealy mouthed rationalisation for and abrogation of responsibility of your drivers actions being those of a total and utter jerk are total nonsense.
He would have had to be an actual saint incarnate NOT to have said anything after your friend behaved like an arsehole who if they’d acted as they did where I live would most probably have been the subject of physical as opposed to just verbal violence.
What I find worrying is that not only do you find it quite normal for your friend to act indefencibly and behave as though he is the aggrieved party but you feel hurt and offended enough to castigate the driver who was actually the victim of your drivers offensive behaviour on a MB no less.
And THEN you are surprised to find that most people have a cosensus that your driver was an offensive little douchebag in the way he behaved.
It may be difficult for you, but try to visualise your friend waiting patiently,politely and very visibly to occupy a parking space after a safe enough space has opened up and then some repulsive little snot bag screams in dangerously early(It would have to be to beat a waiting car into the space) leaving you there .
Would you have felt that the other driver was right in their actions?
Yeah I’ll bet !
You couldn’t make it up.
