Class notes from the School of Hard Knocks

I'm still working on the issue from last Thursday [1], and I'll note some things I need to remember for next time:

1. Even if the fault lies at The Customer site, we're still to blame.
2. Do not close out the trouble ticket with the Monopolistic Phone Company (for they could not find any fault) until the situation is fully resolved, for The Customer (and they will find out) may not understand such actions.
3. Do not taunt the Happy Fun Dan [2].

And the way things are going, it looks like I may be working on this issue all week.
