I have to say that most actors or actually, anyone in the business, would love a gift card from Starbucks. If they're not coffee drinkers, they may drink tea, or water, or juice, or they might like to eat sandwiches, salads, pastries, etc. If for some reason, none of that pleases them, they could give the card to anyone else in the company. Guaranteed!
