An advanced dishwashing technique where you slowly drain the sink and turn the faucet on. This dilutes the water, thus making it less dirty. Add some more soap and VOILA!! Improved dishwater. Used when there are a lot of dishes but the dishwasher doesn't want to waste time draining and refilling the sink, thus allowing them to wash the dishes nonstop, which speeds up the process. Also used to extend the life of the dishwater when the restaurant is about to close to make it last until close.
New Employee: This water is really gross. Shouldn't we change it??
Veteran Employee: Nah. Just give it a transfusion.
New Employee: Isn't that kinda gross??
Veteran Employee: I can tell you're new. In time you'll learn that you aren't paid enough to care.
