Yeah, that's a TAM. And yes, it's insane. His offical purpose is to help you out. His real purpose is to help AWS out by delaying, stalling, referencing to wrong documentation, making you run in circles etc.

The harder it is for you to get some real support, the better he is at his real job. Its a crazy incentive and I'm not even sure if you can evaluate your TAM. My current manager plays softball with them for unknown reasons so we're stuck with the smooth talking asshole. Not that we had one, I've seen almost a dozen in my career and apart from one, all were useless _to us_.
