I have a couple of girls who are skinner's and miner's.
I always ask before skinning someone else's kill(s) because I know it ticks me off completely when someone comes and takes mine, especially when it is something I actually had to work to kill just so I could skin it.
For the mining, I usually end up just traveling around and mining while I explore and open up the map so there are not many people around but I do prefer to ask if someone is fighting near a node (unless they are opposite faction of course *grins wickedly*).
