And if things are good with no bumps, problems, or bad ju-ju? Do you praise?

I suppose it's human nature to complain, to call attention to bad service. It's how we fix things, get attention, soothe our annoyances (or at least make someone else feel the pain!). The opposite takes a bit of work for most people, though.

I have no problem with people who complain, so long as they take note of the good stuff too. Imagine if we spent an equal amount of energy complimenting those who deserve it? I bet it would be a far more pleasant world in which fly.
