I recently had a less than delightful interrogative experience with SFO airport security. They accused me of having box cutters and confiscated my hair putty, because it was .02 oz over the limit for liquid carry ons.
I decided that this was the stupidest thing ever. And that next time I was fake catching a flight, I wanted to attempt to carry on 2 bags filled with jumbo wholesale products, like the ones from Cost Co or Sam's Club. and just play dumb as they haul away giant containers of hair gel, or mayonaise.
