So, I understand the principle behind having separate hot and cold water faucets: you're expected to fill the sink, and then immerse your hands to clean them. The North American method of rinsing them under the running water is faster, but I guess less thorough.
So, I have to ask: what is the point of having separate faucets in public facilities with no plug for the sink drain? Are you supposed to clean your hands by alternately scalding them and then freezing them? Inquiring minds want to know.
