Exercise from Step by Step Serbian by Mirjana Danilovic
Translate the following: "Please, one Turkish coffee without sugar and one black tea with lemon."
The key gives the answer as: "Molim vas, tursku kafu bez šećera i crni čaj sa limunom."
If I understand correctly, "tursku kafu" is in accusative case but "crni čaj" is in nominative, even though both are subject to an implied "I want/I would like."
Why is this? Why is it NOT "Molim vas, tursku kafu bez šećera i crnog čaja sa limunom"?
Hvala mnogo!
