I expect people in any position to know what the hell they are talking about, or GTFO. It always refreshes me when I go into an advanced auto or something similar and ask for a part, the guy asks why, and then can actually part with some knowledge in the situation. Customers want value with their service, not just service these days. I would gladly go pay more if they would hire people who knew what they were talking about. I guess this isn't the case for most though.
