What's That Called Again?

The other day I ordered up a bunch of lighting gear from Paul C. Buff - aka, the AlienBees company. (Which might register as recognizable to maybe 3 of you).  Among that gear were a couple umbrellas and covers that turn them into giant softboxes. But one of those covers was the wrong size.

So I e-mailed the company and let them know that they had mistakenly sent me an 86" cover instead of a 64" one.  Shortly after their business opened for the day I received a reply essentially saying, "Sorry we messed up. The right one's on the way. Don't worry about returning the other one."

I'm confused by this. An incredibly prompt response correcting the situation perfectly in a polite and straightforward manner? What's that called? Custard serving? Costumer justice? Oh wait... customer service! It's nice to see that the rumours of them being easy to work with are true.

It takes some sting out of the fact that I didn't think through why a real softbox would be helpful for my current shoot, which kind of screwed up my plans last night. But that's also on the way to being fixed via good ol' spending more money on stuff.
