So I was flying out of San Francisco on Tuesday.  Late as usual.  I go through security, and a supervisor gets called to inspect my bag.  He pulls out my toothpaste and deodorant, and says “I’m sorry, you can’t bring these through like this.” Nothing antagonistic, or negative, just a statement of facts.  My response: “Oh, I’m sorry, I always have them, and it was never a problem before, what do you want me to do with them?”  Very nicely he says, “Well, we can dispose of them, or you can put them in a transparent, resealable explosive retardant package;  they sell them at the store over there, and I’ll give you a pass so you don’t need to line up to wait to go through security again.”  As I had spare time (5 minutes before boarding), I thank the fellow, take my things, and wander over to the store.

Once in the store, I ask to purchase the explosive retardant package.  The lady says “$0.32, please”, reaches down and pulls out a Ziploc sandwich bag!

Ziploc bags.  Never leave home without one!
