Stop in for a cup of coffee

We have the good ol' Mr. Coffee. I like the way it works. If you pour 6 cups in you get 6 cups of coffee out. My Mother in law has a Bunn and the last water is what you get out the next time. OK if you fill it up and turn it off. But then it isn't instant coffee as designed. The water has to heat up to boiling first. If you leave the heater on 4 or 5 cups of water will evaporate overnight antd your first pot is only 6 cups or so. (bang head) Sorry for the rant and thanks for listening! LOL
