When flying from JFK airport terminal 3, on the 3rd of July 2011 on flight DL184, I thought I should buy some stuff at the duty free shop as I wouldn't have time to do that when I transferred in Paris (Charles de Gaulle airport). However, due to improper sealing of the bag (the store just stapled it together with the receipt), the alcohol was confiscated in Paris. The trouble with the customs there made me also miss my connecting flight.
I could understand that this bad practice of just stapling the bags closed being done in a 3rd world regional airport or on a ferry, but not at one of the busiest airports in the world. That combined with foul-tasting pizza at the pizzeria on the airport and a bookstore with a severly limited selection, left me with a bad impression of JFK airport.
I had seriously expected much, much more from JFK Airport.
