Star Wars fan Chris Jarvis, 31, was told he would have to leave if he did not take it down.
Chris is a member of the International Church of Jediism – based on the sci-fi films – whose doctrine states that followers should be allowed to wear hoods.
But when he protested, security escorted him from his local branch in Southend, Essex.
He filled out a complaint form – and received a formal letter from the JobCentre Plus branch’s boss just three days later.
