Starbucks sources coffee beans from suppliers around the world. They have programs like C.A.F.E. to ensure high quality and fair treatment of suppliers. The beans are roasted at plants in the US and abroad then distributed globally through regional centers to Starbucks stores in over 70 countries. At stores, baristas prepare drinks and food for customers, who are primarily adults ages 18-40. Prices range from $2-5 per drink on average.
