My least favorite Starbucks at McCarren is Terminal 1 across from C14. The staff who were on duty last Thursday around 4pm, were pretty slow, unproductive, and unprofessional. Only three customers including myself. The barista didn't listen to the cashier with my order, and made a hot beverage instead of a Frappuccino. She then had an attitude and rolled her eyes at me when I asked her a question to verify that she made my order as I requested. They could use a refresher in customer service and productivity.
