Sometimes business has to come before pleasure, I know my lady would wait in the parking lot for 3 days if she knew it was important.
But if I was a VC, I would give everyone X amount of time, but have a plan B to talk all day if things went well.
Either way, I wouldn't be booking anything 5 minutes after the pitch.
So he did the right thing from both perspectives. Which is probably why he's rich and has a (presumably) hot wife.
(I know that sounds politically incorrect, but alas, reality often is. To be fair, it probably works both ways: a man won't respect a woman who drops everything for him, either.)
It's not about dropping everything for the other person - I don't think anyone can expect that. It's about picking up the phone and saying "sorry, got to keep you waiting, it's important". Communicating and managing expectations.
It's a pretty minor quibble, I guess, but it just struck me as something rude.
