This is an example of what one opens themself up for when they try to get any kind of cabin service on US based airlines. As I've indicated in previous posts, the safest approach is to purchase any food/drink you may need for your flight AFTER you've cleared security.
The less conversation you have with a flight attendant, the better. I will usually close my eyes when the flight attendant comes by until they've passed. If conversation is unavoidable, limit your responses to "yes," "no," and "I wish to remain silent." Consider yourself lucky the flight attendant didn't try to fabricate a story and say you were threatening him or being disruptive.
The only jerk flight attendant I'm aware of on Contintental is CHRIS BOONE. See the story at:
