Petrol

So I was filling up petrol this morning, getting dizzy from the fumes (or was it the price?) and I'm thinking to myself, why haven't they got that little thingy that holds the petrol pump handle down in Australia? In America you stick the pump in, press the lever, and lock it in place with a little metal clasp. When it's full it pops shut. Here you have to hold the lever yourself the whole time, and for some reason it keeps popping, when I hold it, every 3 or 4 litres, and I have to constantly check to see if it's really full or not.
That, and Trader Joe's, are the two things I miss most about America.
