Two completely different installation "tales of woe" here.

On the one (MNTommyboy), I would just forget about the guy, or give him a "special PIA" rate from here on out.

On the other (BMaxey) it's a completely different thing. Here you have a situation where the two systems will probably be married at some future date, and it's a question of whether you want to be the one doing that work, or have the other company do it (and probably trash you).



Me, I would walk in either case.

I do come back it's to fix what someone else messed up, and I charge a premium rate.
