Keeping us safe

I'm reading the TSA page on permitted and prohibited items in advance of a trip next week.

This was cute. Under Food and Drink, it specifies that you may bring:

Beverages brought from home or purchased before reaching the security checkpoint in a 3 oz. or smaller container and in your quart-size, zip-top plastic bag.

I realize they're saying this to be consistent with their three-ounce rule. But I still chuckle when I think of somebody bringing a three-ounce container of soda. You know, in case they get thirsty.
