I just imagined Sonny, from the musical In The Heights, as the coffee taste-tester.
Usnavi: Here try this one.
Sonny: Another one?
Usnavi: I think I’ve gotten the recipe this time.
Sonny: Fine
-Twenty tries later-
Usnavi: I promise you this is the last one.
Sonny: *under table jittering from caffeine* Y-y-you sai-iad t-t-th-that t-ten ba-batches a-a-ago.
-A year later-
Customer: This is amazing coffee!
Sonny: *dark look in eyes* You have no idea what I went through to get to that point. Worst month of my life.
