Clean hands.

Let's talk about how to use the sink for a minute. Sometimes it's just like every other day.

But sometimes there's a foot pedal protruding below the piping that you need to step on like an accelerator in a car. Don't stomp or it my spray everywhere. Just shift into first and easy down on the pedal.

Sometimes there's a rubber-looking button on the floor that you need to stand on. You can usually stomp here.

Either way there's probably no hot or cold control. That'd involved two pedals and more shifting. Instead, we just get cold.
