"I am a continental flight attendant and do my job well. I understand that the aisle flight attendant was maybe in a bad mood, but if you experienced what we go through you would understand. "
First, you may THINK you do your job well, but it is the paying passenger who ultimately makes that decision. Secondly, I am in customer service employees, and regardless of the stress I may feel, I NEVER let my stress affect my professionalism, no matter how unreasonable I may think their requests are.
"Its almost like the passengers that when we collect trash, take about 20 seconds to fumble around to give us a 2X2 piece of paper. "
Maybe you should slap them so they would speed up the process of making your job easier.
"Probably the most annoying thing you did, is as soon as you walked in, you asked for us to take your coat. There are so many things that go on during boarding that is the least of importance."
Maybe a simple, "Sir, I'll get your coat in a few minutes" along with a smile would be all you need to do to create a pleasant experience for your customer.
I have traveled on UA, CO, AA, WN, and several international carriers in all classes. Some FA's enjoy their jobs and show it by going the extra mile to make their customers feel welcome. Others, like you, do what they think is required to get their paycheck. Maybe, instead of using a "do what is minimally required" attitude, you used a "how can I exceed my customers' expectations" attitude, you and CO might REALLY stand out for excellent service.
