if you're on a call with an account manager and a support person, and the support person is clueless, politely shut down the meeting early, and then schedule a 10-minute with the account manager to tell them the support person isn't helping.

As much as I hate personal relations, I frequently have to "herd cats" (contractors and cloud vendors). On the other hand, once in the while I get an absolute superstar and I work to keep them on my projects as long as possible.
