W: I beg your pardon?
M: I'd like to look into your bag, if you don't mind.
W: Who are you to insist? I advise you to take off, before I call a policeman.
M: I am a policeman, madam. Here's my identity card.
W: What? Oh...well...and just what right does that give you to go around looking into people's bugs?
