I work in a university though I'm not an academic. I do, however, have both a private sector and a teaching background, so what they do is not a mystery to me.
It may be possible that this is a symptom in my particular institution, which has a bit of a reputation for eccentricity, but some of them do themselves no favours. In general I find the academics who are also mothers tend to be the most sensible and realistic. But of, dear god, some of the others do themselves no favours at all.
This is an example of a typical email exchange I had over two days this week
Me: I've discovered a technical problem in something that I know has a very short deadline. While we wait for the support guys to fix it, I can put in a
workaround for you. Would you like me to do this? I will need Information A and Information B. Information B is very important (a deadline)
Academic: Yes please. that would be helpful.
Me: Could I have information A and B please, I cannot put in the workaround until I get these
Academic: Here's information A
Me: I really need information B please.
(At this point I make an educated guess at information B and put in the workaround anyway)
Next Day..
Academic: Here's information B but the deadline was last night.

Part of my job is staff training. One of the items I have to teach academics takes, on average 10 minutes to learn. To be honest, it's fairly intuitive and a reasonable percentage manage to work out how to use it with no input from me. However, for a reasonable proportion of the teaching staff, teaching them how to do a simple task, will inevitably involve an extra hour or so of me having to endure the moan that broadly consists of "I don't see why we have to do this, it's too complicated, the students won't do it, why can't I get a student to do this for me? It won't work, I don't have the time to do this, this is all part of the (insert academic conspiracy here) the faculty staff won't use it, why can't you do it for me?" FFS if they just stopped whinging and got down to it, they would have learnt something that actually saved vast amounts of time freeing them up for research/teaching. 
I qualify all this by holding my hand up and saying I am a teacher, the whinest of all professions.
