The surface area of saucer is higher than the cup.
we know that the rate of evaporation is depends on surface.
so the hot tea in saucer is easily evaporates and quickly cools downs.
thus,most of the members are prefer to sip hot tea in saucer instead of cup

THIS IS BECAUSE OF THE EVAPORATION AND SURFACE AREA.
AS THE SURFACE AREA OF THE SAUCER IS MORE AND MORE TEA COMES IN CONTACT TO THE AIR AND GETS EASILY EVAPORATED.
SINCE EVAPORATION CAUSES COOLING EFFECT BY DECREASING THE AVERAGE KINETIC ENERGY.
