Same as many, rego, overdue fines (which I don't have very often!), batteries and fuel.. I don't mind buying fuel, but I resent the amount I have to pay. Especially if you drive past the fuel station on your way somewhere and it's $1.32 and you go there on your way back and it's $1.42!!

Also I don't pay for water where I am, but I know so many people who HATE when their water bill comes in!
