Robert, there is only one real conclusion here.  He is coming to our shop for services.  He sought me out.  I never went after him.  When doing business with anyone, from a minister, to a trash hauler, there's always gonna be conflict, if the two parties do not agree on certain things.  So far, it's my rules, my place and my time.   He's on a power trip and I'm gonna either break him or send him on his way.  Kinda simple.  No need for reindeer games.  You get to a point, playing Dr Phil and sh!t, just really don't matter.   
I don't need to understand anything on his end.  I do not care what is going on in his life, business or head.  He is in my place, so I rule and he is trying to override that lately.  He wants command.  That's where the "or else" comes in.  As I mentioned several times before, I don't wanna lose him, but I'm not paying games.
Facts are : we letter said can.  We get paid for our job.  He's happy & I'm happy.  He's messed with that and causing waves.   You want me to sit down and find out what's on his mind ??  For what  ??  If I understand him better, is he gonna not be tardy ??  I don't think so, but then I don't think I care to find out, either.  I have too many other things going on and he's slowly becoming a liability.   Ya gotta know when to let go and stop wasting time.  What did Kenny Rogers say ??
