After we'd finished the work he asked me for copies of the receipts
for the materials and he'd square up, when I did so he struck-off his
half of the cost for the downpipes and outlets, on the grounds they
were all mine, cheeky git! I felt like putting a hacksaw through the
gutter at the mid-point and fitting two end-stops.



The cheeky ****.

Shove some expanding foam up his cars exhaust pipe and put dog****
under his car door handles. It's all he deserves.


Expanding foam may have competition.

Fence post fixing foam sounds interesting for a similar purpose.
