Beags, I think we went one better. After weeks of complaints about our grass, and threats from a civilian to report us, we returned from the Gulf. I cut our grass with the loudest thing I could find, then sprayed their grass with Round-Up.
Departing Halton everyone got up to jolly japes and usually ended up paying for them, to get around this we managed to acquire a sizeable amount of waste AVTUR and carefully spelling out the Dicip's name, inscribed the lawn outside his office with XXXXX is a cnut, true to form over a week or so after we had departed the grass died back to be read by all and sundry from the surrounding blocks and the said unimpressed individual, who found after re turfing it still showed up
I have a picture sent from the upper floor of the block somewhere.
