How did Barwaqo Mohamed learn to speak English?

I

She was an immigrant with a journalist who volunteered to tutor her english.

Barwaqo takes free English classes through a program in Cambridge called the Community Learning Center. But her main classroom is Starbucks, where she has worked full-time for the past six years filling orders from countless English-speaking customers.

The job made her remarkably fluent very quickly, and it has given her an unusual vocabulary that includes words like "Tall Skinny Vanilla Latte" and "Chocolate Cookie Crumble Frappuccino."
