Depends on his mood or the time of the day. When he has to get up for work, ( with is crazy early, like 4 - 5 am in the morning ) He needs something strong in his system to snap him from the sleep-dead state. Then he will take his coffee purely black, no sugar, no milk, with lots of ground pepper, cayenne, and cinnamon. When he is stressed he will take black coffee anyday, sometimes even replacing it with a meal. But when he is relaxed and content, he will take his coffee with some chocolate syrup and cream. In the evening, he likes to have some green tea.
He doesn’t like sugar in his coffee or tea as he finds no need of it if he has something already sugary to go with it like a cookie, cake, croissant, etc. those are enough to balance the bitterness from his drinks.
