And being a pilot doesn't mean they know everything. Had a proceeding pilot from another airline start a riot at line up over cold soaked fuel frost on the upper surface of the wing, something that is approved and completely normal on the 737-800. In the end it produced quite some delay and substantial costs to the company, for nothing really.
That said, yes, taking passenger advisements seriously is something every pilot should do. The attitude expressed by Piltdown Man in post 28 is the one i think is the right one.
