anecdotal, but i stopped having them after they were required to put calories on the menu. That and i got common sense and started making my own coffee rather than spending ~$5 per coffee everyday.
With expensive coffee, and an expensive machine, at 10 cups per day, after 100 days (1000 cups), that's $886.36, or $8.86 per day. If you find a cheap machine and good, inexpensive coffee, you're looking at $301.82 or $3.02 per day.
Add in $13/300 paper filters for easy and compostable cleaning, and you're looking at $3.45 - $9.29 per day, depending on your coffee price. And 32oz of vinegar for the descaling ($4) for another 1000 cups, increases to $3.47 - $9.30 per day.
As a bonus, if you're also a Futurama fan, you will experience time at an unusual rate once every 10 days.
I make a batch at a time (roughly 1 litre), call it a couple full coffee cups, without having to wank about with a bunch of tiny per-cup efforts that add up to being a pain in the ass overall. Coffee grounds can go in my compost, or feed the next batch of oyster mushroom spawn. Mmmmm.
