"i fill a mug with milk, drink it down to the amount of milk i want in my coffee and then add coffee & water"

unless they're being weird and saying they're adding unbrewed beans and water to their milk, the implication is they're adding (already brewed, presumably in water) coffee & water

which is adding more water than the water that was used to brew

talk about reading comprehension when you get some of your own, moron
