This Starbucks opens at 5:30 a.m., so if you're in there for a 6am flight it is such a tease to see them behind the counter setting up for the day and you cannot order!
In the mornings there are about 10 people working so it goes pretty fast. That said, the line is ridiculously long since it's the first thing people see on the other side of security and since you cannot bring your coffee through with you, they are all salivating to get frisked so they can run and get in line.
