Well, the fact that is was for a D&D game is irrelevant; this is a basic social issue, not a gaming issue. And it's pretty much Social Behaviour 101; we're not talking advanced techniques here.
That's pretty rude. Sure, sometimes social arrangements get cancelled; but not informing the other party in advance is fairly obnoxious, in my opinion. Shows a complete lack of respect.
If you're not going to be where you said you were going to be, you let people know. It's a very simlpe, very basic rule of social intercourse. It stops people (like you) from feeling upset; it allows them to make alternative arrangements; and, more importantly - it's just what you do.
I'd be pretty angry myself.
