When Michael is called for jury service Arthur decides to go along to support him with other café customers. However ex-con John the Hat's criminal associates mistake Arthur for a powerful gangster, which is fine for Bulent when they try to extort protection money from him but less so for Michael when CCTV appears to show Arthur offering him a bribe. However both are exonerated when Arthur brings to justice the villains and a corrupt judge, accidentally of course.
