The bad co-worker: recognise him!

Everybody of us has experienced the phenomenon "bad co-worker", but let me explain what I learned from my experience (web-developing, coding, graphics):

1. He (the bad co-worker) designs a layout and then he sends it to me for slicing. BUT when I open the layout in Photoshop, I realise that it consists of 200 layers, ungrouped and named with names "layer 1, layer 2, layer 3, ......., layer 200". Believe me pal it is much easier for me to deal with grouped layers in categories like Header, Footer etc and names like Title, sidebar background etc than guessing or right clicking its layout's component to find the appropriate layer.
2. If I am out of luck at all the layout file is merged down and in .jpg format with the sample text (which should be deleted) on it.
3. When he writed code, he does not use "ENTER" button for changing line. The code is a mess, without comments and looks like simple text.
4. When his pc has a problem, he asks the others first and then tries to fix it on his own.
5. He prefer asking the others for finding information (like a website's URL) than using Google.
6. His computer is a mess. The desktop is full of icons and files are totally unorganised so he (and everybody else) cannot find them when it is needed.
7. When a serious problem occurs in his pc, it means data-loss as he does not know the very simple word "BACKUP".
8. He leaves on time even if he is a click away from completing a serious task.
