Why would you ?
Better for him .. caffeine is addictive and not healthy.
Besides that , I don't get the whole coffee-thing .. sure a coffe with milk and sugar tastes ok but a warm chocolate drink or any kind of tea beats the taste of coffee by far.
And people who think black coffee without sugar tastes good either have a very weird taste or just like it because they are so used to it / addicted to it.
Things that actually taste good are those that children usually like.. and children don't like coffee or beer. If you eat/drink anything regularly you might start to like it .. this is actually something that can be developed over time. Especially if there's something addictive in it like alcohol or caffeine ..
PS :
Whiskey just like any other liquor does NOT taste good
no, they are just acquired tastes. i love my coffee black. i didn't at first. i don't drink coffee every day, i'm not addicted. i just think that the flavor of black coffee is so good, there is no need to cover it with cream or sugar. it has such a distinct, full flavor of its own.
same with whiskey. it tastes good straight. you might not be used to it, but once you refine your pallette, its well worth it.
