In my younger years I had more than my share of jws ways of doing buisness. They are always trying to get something for nothing. My favorite is they try to invite you over for dinner in exchange for doing some work on their home. Now when they try that I laugh at them and tell them I will figure up just how many meals that would take. They are always wanting to borrow things. Always trying to sell you crap. I found that if a jw calls you out of the clear blue they want something. What buisness I did with them I always got screwed over. They are the worse for trying to beat the irs. They will try to beat you out of your wages. That is why they like to hire their own kind. All of my experiences may just be mine, but I have heard this for years and now I hear it lot on this site.
My rule now for the past 30 years is that I do not do buisness with witnesses. I broke my rule a few years ago with and elder friend of mine. He is the most honest person I have ever met in the organization which I think makes him very rare. I wrote up an iron clad contract, and we sat down and went over every detail . Never had one problem with him.
What is it about most jws that they think all other jws owe them everything and should do everything for nothing. I have never been able to do that to anyone.
