The average ATT store employee has NO CLUE.
So true. I was investigating weird ATT data usage on my account so I brought in a spreadsheet with dates and data usage. The usage column was in kbps and I got in an argument with the worker-drone as to what those numbers mean in MB. This dude turned to the "manager" with a quizzical look on his face and the manager tried to argue with me as to what a MB was.
Both of them had zero idea what I was talking about and I lost all respect for the people they employ in their retail locations.
