I hate when you're talking to someone and the phone rings so they answer it, thus ignoring you.
It used to happen all the time at the council offices I used to have to visit when I was a council tenant a few years ago. If the caller can't be arsed to come down in person, then make em wait!!!
It's bad manners, and it's 'pushing in'!!
Old geeks don't die, we just incur a fatal exception!
