Have you ever flown on Southwest Airlines?
Every time I have there was something unusual about how the flight attendants assisted us. It helped make the flight fun. Always an attendant re-worked the pre-flight instructions. " . . . In the event of a sudden loss of cabin pressure, oxygen masks will fall from the compartment above you. After you have stopped screaming, pull the mask to your face, . . ." Most times when offering snacks and beverages they were playfully rude. "No, I don't think a diet coke will do it. You look like you need a stiff drink . . . or maybe a slap across your face. How many of our passengers think this man needs a slap? Raise your hand if you agree with me."
Always they run the risk of getting passengers too involved, like the time my seat mate rolled a tangerine all the way down the aisle to the cockpit door, where a flight attendant was making coffee. FYI, the attendant was shocked, but then gave a thumbs up because of the skill of the feat.
But passenger involvement is usually a great thing--like in this video. Have a look.
