The New Coffee, One Month Later

I've now spent over a month dabbling in the new office coffee, produced by the local Starbucks machines. I have to say, it works -- it's OK stuff. I still prefer the brew that comes out of my own coffee pot, but relative to the old stuff, this is pretty good. 

What I don't understand is why some floors have two machines and some have one. I'm sure there was logic applied, but the pattern seems random.
