No, not at all! If you've been in the business long enough, you learn that people have different preferred ways of working. Some will use menus, some will use icons. Some will use keyboard shortcuts. Some will use drag-and-drop. If the bug description doesn't specify how they performed an action, and you assume your preferred way while they used another, you can easily be unable to replicate their problem.

I don't remember any specific instance where I had this misunderstanding, but a coworker had it happen and will never forget it.
