Business: Brewed coffee to-go

Here's another reason why I think Koreans have got it all figured out. Here's what you can purchase at any convenience store of the likes of 7-11. Hot water is provided at the cashout.

Brewed coffee on the go: For people who detest instant granulated coffee.

It comes hermetically sealed, complete with strainer, filter, sugar, stirrer, and not to mention the grounded coffee powder. It's cool because the strainers act also as measuring cups. Pour in enough hot water to fill it up to the brim, and it should percolate into the cup to give you the right amount of water + coffee mix for a medium strength coffee.

The only thing that sucks is: Too little (amount) coffee. Pouring more water into the strainer really thins the coffee out too much.

Good enough for me. Anyone seen this anywhere else?
