Yes mooooooorrreeeee c-c-c-c-coffeeee!!
I think that you should pour the hot water in with the sugar to coffee ratio of 2:1 (S/C), but at this stage DO NOT add the milk!
Now you go to the toilet and when you are all done head back to the tea room, grab a biscuit and pour in the milk.
That way you don't get any uncouth bits in your brew!
Then return to your desk and inform us how it went down.
