my friend is a barista.
That must mean they are a coffeehouse employee who prepares and serves espresso-based coffee drinks.
yea they work at starbucks
It's hard to believe that Starbucks has been around since 1971, I thought they were fairly new.
thats still quite new for a billion dollar business
I suppose that's true, they're certainly expanding quickly, as of 2016 they had 23,768 locations worldwide.
wow thats crazy, its so popular.
So popular they're considered the main representative of "second wave coffee" as it's called.
