Keys handed over - Hurrah! Hang about - What's this Stuff ??

Just when you believe that you're actually getting somewhere after lots of waiting about and frustration at the continual paperwork, having had the go ahead from the solicitors to pick up the keys so you can actually do stuff, (loads of stuff actually) you're confronted with this

stuff !!            

Now I'd have thought my

luck was in having a manhole in the middle of the cold room/cellar. But, on closer inspection it seems that this is the first 'stuff ' that will need to be sorted out. It wasn't even on the list of stuff to do. It isn't actually what you're thinking - It's solidified Fat and Oil that the previous hot food takeaway owners poured down the drain. It's gonna take more than drain rods to move that lot, it'll take 'money down the drain' with it.
