hello all.i was working last night,there was a road rage outside
my workplace and i happened to see it.so,this was what
happened.

ignore the date.i have to use a picture to describe.
Car A parked at the red circled area to pick up the groceries
from his wife.often,there are cars parking there to pick up
groceries but this time round,Car A parked in such a way that it
was blocking the traffic.If he parked properlly,the cars behind
will be able to go past in between Car A and the cars parked at the
lots.
The driver of Car A did not consider the fact that he was
actually blocking other cars' way.He came out of his car to help
his wife to put the groceries into the boot.
When the driver of Car A just came out of his car,Car B (from
the back) horned him because he was blocking his way.The driver of
Car A simply ignored and took his own sweet time to put the
groceries into the boot.Moments later,there was a little jam behind
with 4 more cars behind Car B.
After puting the groceries into the boot,the driver of Car A got
back into his car while his wife went to return the trolley.Car A
drove forward abit and stopped again to fetch his wife from the
trolley point.Car B horned him again.
Next,the driver of Car A came out of his car and walked towards
Car B.From what i saw,he attempted to open the door at the driver's
seat of Car B.The driver of Car B came out and i saw Driver A was
pushing Driver B.They pushed each other and stopped when their
wives came out to stop them.
So,whose fault exactly is it?
