Here’s a placard (larger image) on a parking shuttle bus at Dulles International Airport, outside of Washington, D.C.
I’m very appreciative that they let me know, well before I enter the terminal, what I can eat, and whether it’s “pre-security” or “post-security” dining. So I can plan in advance such critical traveling strategery as, do I buy my double mocha skinny latte here, by ticketing, or there at Gate B, after I’ve been body cavity searched?
