Nowadays I get a lot of sales advertise for some package coffee which is already glinded by fax or e-mail.
I believe that the best way to serve some coffee is to glind the coffee and brew it soon before serving some. Maybe using some "package" stuff is a lot easier but tasty stuff needs you more time to prepare. We can get a can coffee with a hundred+ yen through a vending machine but that is not what we provide. Each and every time when customers show up to the breakfast tables, this simple process is repeated in our place. It just takes some minutes to 10 at the longest. Perhaps this is something tiny accommodations can offer :-)
