Bossie gets her own coffee and makes tea for me, too (she's well trained and only seven months in the job
) and I do the same for her. We ask each other if we want tea/coffee whenever we are making one. I make coffee for our Chairman when he's in the office, but he usually gets his own.
We have meeting rooms with coffee/tea machines which are always available so people get their own drinks. If visitors come to the CEO's office, where I work, then I usually prepare their refreshments - dust off the best china and tray and put biccies on plates etc.
Making refreshments is not part of my job, but I don't think it's demeaning.
