In my experience many just tighten up with little regard for what is needed. I tend to look at the VW figures for some items but not necessarily use a torque wrench eg torx screws for holding plastic splash shields in place. VW also give a figure for the battery clamp bolts. I would think that very few would use a torque wrench or even know that there is a figure for these.
Our Polo had a full dealer service when I bought it. The first time I tried to undo the filler/level plug in the gearbox it was so tight that I needed to use an air impact gun to undo it. It has stretched the aluminium so now doesn't seal as intended.
The first time I undid the oil filter on my T4, it was so tight the I tore the hex that was welded on the bottom.

I have also read on the T4 forum where someone tightened a cambelt tensioner so tight it crushed the aluminium portion & failed soon after.
