Crashlanders "Gone to get juice" quest

I'm doing side quests for the guys in Forterra HQ. I think it's Justin who wants juice. The quest instructions normally give you a good idea of what needs done such as "Bring Mark 8 logic gates and 6 timers.". I just remember Justin saying he likes orange juice, my guy says "Good for you. Then the quest comes up "Gone to get juice" and that what the instructions say as well. Not "Bring Justin X juice" or anything. I don't even know how to get orange juice besides /unlimited and I really would rather not cheat. What am I supposed to do here?
