Just think, how many times have you gone through an airport. Did you pack something you shouldn't? Like an orange, but TSA asks you—did you bring any fruits or whatever. For me, I'll say “no” because I still want to eat that orange after I pass the x-ray. Let them dig through my bag and hold up the line for a damn orange.

Why? Because airports are crazy expensive. Tangerines/oranges/apples can survive days without refrigeration. It's enough sustenance to get by during long travel. Especially, if you can't eat gluten.
