This is one thing that differs between countries.
In Sweden... You have a sink split in two sections, one that you filled with dishes+water, one for rinsing. My parents yhsed a dishwasher, and I later had a dishwasher as well.
In the UK, my sister uses a wash bucket. This is the only place I've seen this.
In Greece, dishwasher again. The sink is also split like in Sweden.
In Japan, washing dishes in a single large sink under running water.
Edits:
* The UK also has those braindead hot and cold in separate faucets on each side of the sink. So when you wash your hands, either you're wasting a ton of water, you're using cold water, or you're scalding your hands. Will never understand that. And this is in a NEW apartment!
* Also, many brits I've known don't rinse their dishes... they let them dry with the soap on them. Also inexplicable.
