My favorite is by far the biscuits! Yummy!
Here's a good one for you - last week I was in IAH-BOG in seat 1B. Dinner was choice of pasta/chicken/mixed meat - I ordered the pasta. When the FA can though to clear the salad plate I was still eating. He served everyone else the entree, came and took my plate, and then informed me that they ran out of pasta, but I could switch to chicken - I'll eat almost anything but chicken so I declined politely not wanting to cause a stir - but I was pretty burned - i understand that "my choice may not be available", but I never thought that my choice would be given to someone else if I didn't eat fast enough.
