I don't drink coffee, but I've drank a lot of tee from such cups. Cold drinks too. But with hot tea I've found it's easiest to hold them between your thumb and index or middle finger opposite one another right under the much harder rim. Not squeezing, but letting the rim rest on your fingers, bearing the weight of the cup. When you drink, don't do it with your thumb toward your mouth. Rather use the middle of the free side of the rim. When the rim is in your mouth, raise your hand a little, effectively tipping the cup.
