The only way of dealing with The Porter.

Finish the job properly or he'll bounce back up on his little spring. Nevertheless, he'll still shaft you on a Sunday night, and the next thing you know is that you're drunk and watching 'Eternal Sunshine of the Spotless Mind' while drawing crude maps of the revenge. God that revenge will be great, when all the vampires move in from the left of the page and bite him in the FD60. Keeps out fire, but not claw and fang, you blustering stain.
