On "my" airline, we have 300+ punters in steerage each with two 10" long chopsticks that can be sharpened with a pencil sharper and turned into lethal weapons in a minute!
This whole post-9/11 feeding frenzy that the $6.50/hour mental midgets have embarked must end NOW.
I deliberately try and slow the whole inspection process down (especially in Canadian airports, where it's completely out of control) by slowly and deliberately unpacking things, asking the inspection orifice (I mean "officer") if he/she would like to see more functions, taste my toothpaste, try the mouthwash, see the batteries, etc., etc. You can see the frustration building as you tie them up with trivia. Don't you get upset, frustrated and exasperated...take it to them.
Works for me.
