Tasting somewhat like tar flavoured bile, machine coffee is a form of orally administered caffene. It’s sole purpose is to shock you into getting back to work. It is only barely fit for human consumption; an inspiring drink for ‘knowledge workers’.

An artists impression of a coffee room in a regional financial institution…
At the regional financial institution where I work, coffee is provided on each floor by a number of vending machines. The machines do not charge, yet we may be paying a high karmic price for their continued use:
Press a button and the device will offer to dispense any of seven kinds of fluid ranging from insipid tea to acrid coffee. A further button press will allow you to sweeten your beverage. As far as I am aware, nobody ever presses these additional buttons. These drinks cannot be improved by mere sugars.
My usual machine beverage is “Kenco Really Smooth“; an example of wishful-thinking in product naming. The drink is neither smooth nor real. It has the appearance of runny treacle, and becase it is served in a miniture paper cup it goes from scalding to ambient temperature by the time you have got it back to your desk.
