I freelance and therefore I can be a jackass without direct monetary repercussions, perhaps that's why I don't view it that way.
Because I struggle to think of a lot of situations where I've been unable to replicate an issue a Client has reported where it hasn't turned into a miscommunication/misunderstanding of some sort.
I don't remember any specific instance where I had this misunderstanding, but a coworker had it happen and will never forget it.
I personally see it all the time, but I interact directly with my customers and it's always possible I'm terrible at communication. They'll say things like "X doesn't work on page Y", and It'll end up being a problem with a single link they clicked on because the data for it is such that it causes a problem (that sort of thing).
They don't know that's the issue either, you have to work with them on it.
