Apparently her companion had woken before she did and made the courteous decision to order them breakfast and wheeled the cart to her side of the bed.

Rather than speak or try to wake her with something along the lines of a tap on the shoulder, he just waited near the window sipping from his cup. He had to assume the smell would be enough to slowly stir her awake gradually.
