I was always ready to be part of the solution, so I don't think I was being empty when complaining about things. But I have to add that I wasn't maximizing for appearing polite. I never cross the line of not being respectful, though.
Indeed, the management could have a different idea of what was an ideal direction. I just happened to disagree. It was a very small company, so I don't think I had a lot of different information. But even if that was the case, this was a good opportunity to have a perhaps heated but interesting discussion.
