If I instead complain about having found a problem that everyone else so far in the particular situation has missed, especially including the key phrases "How was that missed?" or "Did no one think to...?" ...then yeah, that may well be a complaint about the other people who have handled it, although it may be more specifically a complaint about slovenly troubleshooting, laziness, and ill-advised and unjustifiable ignorance in a person who should know better.
Ignorance, however, can be cured with education.
This rant was brought to you by a combination of finding an obscure error or two in some documentation, several instances of a multi-tech cluster of sequential wrong or incomplete answers, and a few frakking end-users who are determined that because they are getting an answer that they don't want to hear, that we are the ones who are technically wrong. It doesn't work that way, sweetie.
