I have to disagree with Sergio's comments that AA employees are incompetent. The example has nothing to do with the way an employee does his or her job -- or if they are incompenent or not.
There are times when AA boards in row order only -- it gets people on the plane faster. If people learned to step into the row while the loaded the overhead, more people could get by and the flight would load faster. If they are running late, I would rather have them board this way so we can get on the plane and get going -- so I can make my connection.
I give the AA folks (and all airline employees in general) alot of credit. Thinking about the number of people they see each day, the number of people who yell at them, blame them, and are generally not nice to them, I can see that they may have a rough day or come off as rude. It has happened to me and I take it all with a grain of salt. Just get me to where I am going as quick as possible and as safe as possible...
