I've been away from the retail travel industry for five years now (except for Driving4$$). I remember doing the electronic visa application for clients heading to Australia (no money required) but can't imagine what a prospective, inbound "tourist" must think when being confronted by the ESTA application form (not to mention the $14). I don't even know what some of the referenced "conditions" are. It's sort of like the questions required on a handgun application here. If you answer "YES" you're in a shit-load of trouble.
Stumbled upon this, guess it says it all.
I know what some of my pax say after arriving at Dulles (IAD) - - both US citizens and "visitors," - - no wonder my tips suffer.
