Scott Adams recounts having his 4 ounce bottle of shampoo confiscated at the airport because it exceeded the maximum 3 ounce allowance, even though the sign at the airport said it could be 4 ounces and there was only about an ounce left in the bottle anyway. The money quote:
For a fleeting moment I considered reasoning with the TSA guy. Surely he could see that the liquid part of my container was minimal. But one look in his eyes told me that thinking wasn’t his sport.
Discretion is, they say, the better part of valor.
