It isn't a matter of "one negative experience", it's repeated experiences over time dealing with Neanderthals who somehow survived extinction. The occasional once a year traveler might have "one negative experience". My wife & I used to fly somewhere about 30 times a year, which translates into at least 60 interfaces annaully with TSA. TSA as an organization is a total failure. If they didn't have a captive "customer" base (the word "customer" in this context is a farce, given that nobody in his right mind would voluntarily choose to be irradiated, groped, poked & possibly needing delousing), they would have been out of business by 2003.
