Let's use two gallons of water to get one cup of water

I'm always amazed to watch the antics people go through to get a cup of water. I've already documented the "hot water over ice" technique.
So today I'm in the break room micro-zapping my lunch. A lady comes in. She heads to the sink, right where I'm microwaving, and LEANS on the hot water tap to insure it is turned well off. She then turns ON the cold water, full blast. I mean I have to step back to keep from getting splashed on. She heads over and picks up a styrofoam coffee cup. She fills it about half full of hot water out of the coffee maker. All the while the cold water is on full blast, with water splashing onto the floor. She then turns the cold water down, sticks her finger in it (it's Texas, Summer time in Texas...there isn't any COLD tap water). She then sticks her half full cup of HOT water under the COLD water tap. The one she just ran for two minutes to get COLD water flowing. So she has half HOT water, half COLD tap water (and about two gallons went down the drain) in her cup. She drinks some of the water, dumps the rest and tosses the cup in the trash. She then makes SURE the sink taps are off. I mean she leans on those. I pitty the next person who tries to turn them on.
