Glad to hear that you worked things out that way.
I sometimes worry about some of the advice that is given here. It often seems like using a sledge hammer to crack a walnut.
I'm not going to read back through all the post in this thread to see if anyone was guilty of that this time.
I can't see that anything is lost by what I assume was a mature, sensible but probably determined approach which on this occasion seems to have led to a satisfactory solution. A lot of things can be settled by sensible negotiation.
if that hadn't worked, you still had the option of later using the heavy handed approach which, if it had been your first move might have make him dig his toes in, even though he was in the wrong.
