There is something worse, that being someone else blowing the keg. You get off work, drive home, strip off the accoutrements of the day, and clunk... no beer. The other person got the "awe" moment, you're left with the wtf moment.
I accept mystery keg blow anticipation as a fact of homebrew life. I have two cures. A lagering freezer better racking. Cold reserves, that can be moved without sucking up yeast.
