JohnPhx-
In the old days when I was young(er) and working, the same annoying things to deal with.
At least today we don't have to stay off the phone "just in case someone calls" and we have a lot of "toys" including the PC to amuse ourselves while waiting.
We have the option of actually accomplishing something like writing your will or playing computer games while waiting.
Good thing about
Comcast repair guy showing up late - they usually comp you - $20 or 3 months of HBO.
With other repair guys, I'm usually so grateful that they show up at all, I'm willing to forgive tardiness. (You cannot know what they got into at the last job.)
Otherwise, you sound like a typical man. That's why they usually die before their wives.
Do yourself a favor and Chill!
