Alec Baldwin was passing time sitting in his seat on a flight at a gate and not going anywhere, playing "Words with friends", when apparently a flight attendant "reamed" him to put away his smart phone. His swift lack of cooperation necessitated removing him from the flight.
Some flight attendants on domestic flights have gotten into the "rhythm" of doing their jobs methodically and harshly. They are overworked, underpaid and unhappy, and they have no hesitation in letting you know it.
If you don't turn off your smart phone, bring your seat to upright position or follow their directions, their voices will remind you of your fourth grade teacher chastising you.
Foreign carriers compete harder for your business, and their flight attendants who are better trained, treated and paid show the travelers the respect, service and smiles that have become so rare in the cattle car conditions on domestic routes.
