Commercial Coffee Brewer with Upper and Lower Warmers

It works as described. ONE NOTE.... it would be nice if there was an auto-shutoff. We use this on the workplace, so it was left on overnight and the coffee pot dried up and we were greeted to the smell of burning coffee the next day and a ruined pot that was stained and we could not clean and had to throw out. Surely this is a safety hazard and could've exploded the pot and even worse a fire.
Working for the government......The powers that be decided after years and years (I'd say clear back to 1883 when our hospital was founded) of employees happily making coffee with the various coffee makers of mere mortals (like Mr. Coffee himself), that it was far too dangerous for licensed medical professionals to operate advanced home coffee-making machinery in the break room unless it was officially sanctioned by the safety committee, security, administration, and probably as a state institution, an act of legislature. Not that they had any intention of providing the officially sanctioned professional grade machines. So I purchased this miracle a month ago and once again, the patients on my floor are being cared for by professionals who have had their daily dose of fuel, available whenever they need it thanks to the double-warmer model Bunn I purchased. It brews fast enough for a nurse's break, which really in no break at all, delicious ambrosia of the gods!
