As an on-time pax I am fed up with being inconvenienced and stessed out by people who can't give a sh1t. E.g. "Will I make the connection at the other end now we've lost 20 minutes?"
Off with their bags I say!
BTW, don't want to change the subject, but with the new RFID technology a tag can be attached to the boarding pass, and can track the pax whereabouts in the terminal. Late pax could even be targeted for automated announcements channeled only thru the tannoy near them "hey that's enough time in the toilet Mr. Jones".
