Vicky, I didn't any drought orders had been issued in the UK yet. I know that a lot of places (including where I am) fall under the hosepipe ban and stuff, but that doesn't stop you from washing the car like a full monty drought order.
I have seen our next door neighbour watering his garden and rinising his car with the hose a few times. I mentioned to him its taking the piss a bit when everyone is not doing so, but he carried on. Yesterday he was doing it again so I went and said 'Do you hear about the bloke in the village who got grassed up for using a hosepipe on his garden and was fined a grand?'. 'No' came a rather worried reply. So I suggested that if he stopped using it, and asked his annoyingly squealy noisy child to quiten down for at least half the afternoon, I wouldn't be the one to grass him up.
Worked too! The kid was told it could only make noise for half an hour!
