Joseph Kynaston Reeves, 40, from Northern Ireland, wrote the strongly-worded letter to Brand after he attempted to enter the office where he worked.
While Brand thought he was sticking up for the less privileged by attempting to gain access to the RBS London office armed with a megaphone and a camera crew, Jo complained that he was unable to eat his rapidly cooling paella because security closed the building's lobby.
In a post on his Facebook page tonight, Brand apologised for holding up Jo and making his paella go cold, as well as speaking to him aggressively.
But he refused to say sorry for the lockdown.
"I’d never knowingly keep a workingman from his dinner, it’s unacceptable and I do owe you an apology for being lairy," he went on.

The comedian and activist explained that he had attempted to enter the RBS building because he and filmmaker Michael Winterbottom are making a documentary about the economic crash.
Brand also hit back at claims that the lock-down was a publicity stunt but said Jo “could be forgiven for thinking so”.
“If I needed negative publicity (and, believe me, that’s all talking publicly about inequality can ever get you) I could get it by using the “N word” on telly, or putting a cat in a bin, or having a romantic liaison with the lad from TOWIE,” he joked.
In the lengthy 1,019-word post, Brand explained his stance on the banks, public money, and bonuses in his characteristically verbose style.
"Put simply Jo, the banks took the money, the people paid the price," he wrote.
He concludes by urging Jo to get in touch, and asking him to join him for a hot paella “to make up for the one that went cold”.
“When I make a mistake I like to apolgise [sic] and put it right. Hopefully your bosses will do the same to the people of Britain,” he added.
