Crikey Jim.. I think you should have your meter checked.. Never paid more than 150.00 and neither have my tenants!!Water bill of 1000 is good for daily showers for 7, cooking, cleaning and waste.
Bit concerned about your Cinema bills too!! Popcorn + 4 packet of crisps a large Sprite and a ticket only sets me back a little over 200.00!!
As you say.. 68K is pretty good living IMO..
