@Trapper0 - coffee snob here and would-be complainer if there wasn't coffee .....
Yes, provide coffee for free.
My advice: get rid of the expensive Keurig. Buy a cheap drip coffee maker (a Mr. Coffee) and provide ground coffee that people can make a pot for themselves. This will cost you pennies per pot (which is why offices provide free coffee - the expense is practically nothing). It doesn't have to be super fancy coffee either, but if you buy a really nice coffee jar and dump the grounds into it, it will seem fancy and it could be the cheap stuff. You can provide sugar, ultra-pasterized creamer that doesn't go bad, and a few packets of a non-sugar substitute. Most coffee drinkers will be FINE with this arrangement, they just need a little pick me up in the morning - it doesn't need to be an expensive add on. Most coffee drinkers know how to use a basic drip maker, but you may need to provide some easy directions - will take you a few minutes to type up.
The initial cost to set this up: maybe $50 total. If it costs you another $50/year I'd be surprised.
And, if you want the social capital, provide a countertop composting crock for the spent grounds and filter because these are the best composting material. Then just dump it in your garden. It's great for the soil. (bought my bin at Plow & Hearth for $20).
Although you can charge for pods if you want using the Resolution Center. Just make sure you announce it on your listing that there is a charge.
If you want a list of what to buy since you aren't coffee drinkers, I'd be willing to provide one. Just private message me.
