Coffee's a great idea. (I don't drink coffee, so I never think of it.) It won't work for my husband's office since they have a single-serve system, but my office still uses a traditional coffee pot.

Rum Cream, sadly, my office would be cross if I brought some in to share... and there are too many people to bring everyone their own to enjoy at home.

I never thought about vanilla/spices! That's a great idea!
