Spike's mug - Kennedy disrespects - Willow and Xander set her straight

This is a pretty short fic I've read some time ago, where Kennedy is being somewhat contrairy to Spike in regards to a mug. Turns out it was a mug Joyce had bought for Spike to use for his blood.
Willow and Xander basically tell Kennedy off, taking Spike's side, making it clear there's a lot of things she doesn't know about the past relations between them all.

If anyone could point me in the direction of this little fic, I'd be mighty greatful.
Thanks in advance ; )

Ah yes : )
That one always stuck in my mind for some reason and it was a shame I lost it.
Thanks for giving it back!
