Two men have been given life sentences for shooting a stranger dead after a row in a queue at McDonald's in Brixton.
28 year old Horace Campbell and 18 year old Liam Douglas-O'Callaghan were found guilty of murdering father-of-four Devon Scarlett.
Mr Scarlett and Campbell got into an early morning spat at the fast-food restaurant in April 2010.
They were escorted outside by security guards but the row carried on and the two strangers agreed to meet in a nearby street for a shoot-out.
Campbell called Douglas-O'Callaghan to bring his "thing", or gun. Mr Scarlett appeared to make a similar call but no actual call was made.
The court heard, "Devon Scarlett acted with foolish bravado, behaving like a tough guy, but whatever he said and did, he was not armed."
Campbell, who had been drinking, followed Mr Scarlett into Marcus Garvey Way and fired three shots, two of them hitting the victim.
Campbell said: "You are not so hot now", before walking away.
Mr Scarlett, of Croydon, who was born Raymond Mitchell, died a few hours later in hospital.
Campbell, of Anerley, and Douglas-O'Callaghan, of Tulse Hill, both denied murder.
Detective Inspector Henry Lindsley said: "Unbelievably, Devon Scarlett's murder was triggered by the most minor of incidents that Horace Campbell chose to involve himself in."His arrogance and obvious disregard for life is evident when, even after Mr Scarlett walked away from him, he continued spoiling for a fight."
