One company I worked at had a Flavia machine. Flavia is expensive as hell but the packages always work. Then they got rid of it for regular coffee. I left. (One of many reasons).
The next company had regular coffee and then "upgraded" to a Keurig machine. Every other day the machine would overflow is some spectacular fashion. I left.
My current company had regular coffee,was acquired and a perk of the new megacorp is Flavia machines in every office. Happy bee.
The patent on the Keurig has run out, so they are going to try and borrow the playbook from HP/Lexmark/et all? Hahaha. Sell short.
