I'm a little confused

[moss6886]

I've run across several fics lately (all by different writers) that assume that vampires in the Buffyverse have a dulled sense of taste.  Shouldn't they technically have a heightened sense of taste, since their sense of smell is enhanced?  Or is this a canon reference that I've missed?  Puzzle, puzzle...

(My favorite explanation for vampires not eating food, so far, is that they just don't care to deal with the associated bodily functions!)
