Yeah, I got a pretty glass Japanese teapot with infuser for my office
and a filter cone and grinder for coffee. For about five bucks I added
a "frother" gadget and got a box of half-and half single servers at Sams
that don't need refrigeration.
Now I can make Starbucks but better at my desk--with less sugar and
using better quality (organic) coffees and teas.
I estimate .50 per serving or less.
I'm stupid cheap--it's my Scottish soul I suppose
BUT, I also have expensive taste I can't afford at the moment.
But I'll get there, by golly. . .
