Well, well, well....
What a difference a day makes. Demo Guy called us a little before Noon today with a proposal.
He wants to fix the problems we brought up yesterday and one other major problem that we didn't notice until he had left. I told him I'd have to call him back after talking to Karl about the proposal Demo Guy offered. And, after a long discussion between Karl and I, we agreed with the proposal.
We will be watching pretty much every move this guy and his crew makes. I'm 100% certain that we all want to be done with this project and done with dealing with each other. And, frankly, Karl and I want to move on. (But that's not to say we won't take appropriate action later on.
