There's a bit in a Bond film - I don't remember which one, but it was largely set in San Francisco. Bond and a Bond girl were battling bad guys in the SF City Hall, during the course of which the place gets set on fire. Bond and his BG escape unharmed, of course, and since the people who actually set the fire have long since vanished, the cops naturally figure Bond for the guilty party, and start to grill him as to just what the hell he and the girl were doing there after hours in the first place. Unruffled, Bond waves their concerns away, and gives his usual suave introduction of himself as 'Bond. James Bond.' The policeman basically says 'I don't give a crap', and starts to arrest him. You can practically see the gears clicking into place as james realizes 'oh, right. SECRET agent. Whoopsie.' It's a great moment.
