Our recent travels left me with a mental picture in my mind in which an airport bigwig is directing his subordinate.

Bigwig: “We have a new rule.  No more liquids carried on to flights.”

Peon: “Yes, sir.  Does that include water?”

Bigwig: “Absolutely.  Water represents a grave threat to our national security.”

Peon: “Even newly purchased, still sealed bottles?”

Bigwig: “Those especially.”

Peon: “Uhh . . . how would they–?”

Bigwig: “Ask no questions!  Just take the water, especially the highly dangerous bottled water, from every passenger.  Show no mercy!”

Peon: “Yes, sir!  Um, what about our airport water?”

Bigwig: “Oh, that’s no problem.  In fact, we’ll take the same bottles the passengers brought in and sell it back to them at inflated prices.  That’ll help our profit margin!”
