Driver blocked a disabled driver from reach a legal space by cutting whilst reverse lights were on, left disabled driver not in a space and blocked them from reverse if to get out. Proceeded to go into a shop (clearly on something as unable to walk in a straight line) by a litre of alcohol and then proceed to stumble into their car and nearly take the mirrors of their car and giving the disabled driver who was clearly overwhelmed by the situation a hand gesture whilst they were trying to get in their car. Drove as close as they could to the open door as to intimidate the other driver. Proceeded to accelerate harshly down the road before slamming on the breaks and preforming a u turn.
