Pat down--well, do you want the Turkish policewoman to take you into a room 50 ft away from where you just said "see you on board" to the captain (husband) she asks for a pen to complete the forms with the former name on your passport (wrong) then sticks her hands up your sweater to check your bra and says ok--go back?

Sorry, I'll take some stupid lacivious grinning idiot who doesn't know who I am after I leave the scanner and if he or she wants top look at an image that resembles body part--prurient interest is nothing like being physically violated.
Trade off?
