I won't mention the airport .... but I recently gave 4 bottles of wine to a helpful agent. for me, ^ for her. The bottles had been bought duty free and carried into the country. However, I then had to overnight at an airport here in the US due to a canceled flight and knew that I could not carry them thru security the next morning.

And I certainly was not going to drink a whole bottle (much less 4!) in my hotel room that night.
