Andrew Clark, 43, was fatally injured when Demeish Williams, 30, hit him outside the supermarket on Upper Elmers End Road in Beckenham.
Footage first shows Williams entering the shop, where he got into an argument with Andrew who told him he couldn’t push in front of him and his wife in the queue.
Williams can then be seen leaving the shop and jogging across the road to his car, leaving his groceries, putting on a facemask and returning to the shop to strike Andrew.
In court on Friday, Andrew’s wife Cairistine said to Williams: “You took him from us that moment you chose to walk back from the car and inflict the violence that ended his life. Why did you come back? Why didn’t you walk away?”
Cairistine said: “I will never understand why you came back that day. It was deathly dark and you left a small child in that car. When you went back to the car you didn’t leave. You didn’t check on the child. You put on a face covering and came back.
“What type of man choses to kill rather than simply walking away? The type of man who is not a man but a monster.
“You killed Andrew then cowardly ran away. You are a coward. You are a killer. You are a monster.”

Andrew’s daughter also wrote a statement which was read out by one of her aunts.
She wrote: “I was 13-years-old when my dad was violently killed and I had to spend my 14th birthday without him.
“My dad wasn’t just my dad, he was my best friend. He called me boss, because he said he would do anything for me.
“Our bond was unbreakable from the first moment he held me. We did everything together.”
She asked Williams: “Why did you have to do this to my dad? Why haven’t you shown any remorse. No apology. No explanation. Just silence.”
She told Williams her dad believed in fairness and that’s all he was standing up for that day.
“You get to keep your family whilst you destroyed mine in the most brutal way,” she said.
Andrew was described as a “brilliant dad” and “the man who held their family together”.
He was a massive Newcastle fan and had watched his club win the Carabao Cup final on TV that day.
He described it as one of the best days of his life but an hour later he was attacked.
He sustained critical head injuries and died in hospital three days later.
When bus driver Williams was arrested at his home on Fir Tree Gardens in Croydon, his mum said “I know what happened. He told me. The man called him c**t.”
Williams pleaded guilty to Andrew’s manslaughter and the plea was accepted by the Crown Prosecution Service, something which Cairistine said had left the family with “no sense of justice”.
Williams will be sentenced on Thursday.
