All of us (well, all of us that actually LIKE dealing with people) have helped someone struggling at one time or another.  However, there will come a time when you're up to your armpits in work and the last thing you need is a civilian by your side, talking to themselves and convinced that everything they find is the most interesting thing that has ever happened to them (or you) -- EVER.  When you just don't have time, you have to follow the advice of the Dog Whisperer:  "No talk; no touch; no eye contact."  :-)    

 When you DO have time, but you run into someone who is researching because of an issue not for pleasure, you should be careful to identify yourself and state that you can help, but in an unofficial capacity and you assume no liability whatsoever -- that their question should be handled by a title company (or attorney).  Just cover your butt.  As for charging for this service, I don't think it's practical (or even worth the effort).

Incidentally, I always try to help new abstractors in my counties.  I was helped by a lovely woman -- who is still my friend and now subcontracts to my company -- when I knew absolutely NOTHING and I am eternally grateful.   Good deeds don't always backfire: I helped a nice old codger by showing him where the old plat books were and where the old buried-in-the-basement assessors' books were.  He said that he's abstracted for decades (although not in that county) and now just takes the occasional order when he feels like it.  He called the next day with another quick question (which I could answer by logging in via my connection to the county).  He said he would recommend me to "others."  His "other" turned out to be his son who owns one of the largest title companies -- with several offices -- in Michigan!  I'm still working for them years later.

 Sometimes nice guys finish FIRST.
