American. We have one but we hardly ever use it. Which is kind of stupid because we're always arguing about whose turn it is to wash the dishes..wow -___-.
I use a dishwasher, of course, because this saved water and electric power. My dishwasher need only 1.1 Kwh (E) and 13 litre water for one tour. I really take care of the nature and my money bag.
I didn't have one growing up so I got use to doing them by hand. I find it faster to do them by hand and I usually do a better job. My dishwasher sucks.
