I wonder if said Blobby is the same person who:
- trimmed the trees with his tips in BFPO47 (perhaps excusable for a first tourist
)then came in grinning (perhaps not so agreeable
).
- caught religion and turned up one Wednesday having forgotten to wash his forehead
- mastered the art of the Tactical PVR (in the days when the waiting list reached 8 years...) to wangle a QHI course followed by 28/Sek Kong...
If so I suspect you'll need to pull up a very comfy sandbag before everyone's used up all their stories about him!
Re poo/DNA, I'm told that unless significant amounts of other, er, bodily matter exists within the sample then - assuming your miscreant didn't have Chalfonts/Emma Freuds - it is extremely unlikely that any identification would be possible.
