As someone who works in the travel industry one thing has come very clear to me. The general public are ignorant, border line stupid. There questions are to weed them out and keep them off my flights. I have friends who are travel agents who get asked how long it takes to drive from LAX to HON. Yes that is DRIVE like in a CAR! Do you really want this person in the seat next to you? If they are that challanged how easy would it be for someone to pass on a little package to them? Think about it. I just live with the little questions and get to the airport a bit early.
