My Favorite ≠ Your Favorite
Just so you know, people have very different tastes. What we like might not be your cup of tea, even though we would rather drink a cup of tea than coffee. So, if you go to Starbucks and ask an employee to make their favorite drink for you, prepare for a world of disappointment.
This particular employee has a soft spot for iced Americano, black. If you prefer something on the sweeter side, such as a venti caramel Frappuccino with extra caramel drizzle, tell them that you want a venti caramel Frappuccino with extra caramel drizzle. Seriously, how hard can that be?
