ask them what regulation it is against?
if they moan get an rcd socket and rcd extension lead preferably in pink so it stands out more lol
As shanky suggests, ask them to point out the exact regulation this occasional extension cable contravenes, and guidance (if necessary) on what method of fixing this occasional extension lead to the pavement they suggest!! If nothing else, it'll be interesting as to what they will come up with!! lol!!
