I just listened to this sentence and I heard the voice that I call "second female voice" (she's Brazilian, as I understand). She always speaks slowly and clearly. I distinctly hear her say:
- Ĉu ni rajtas ... sidi ... en la ... kafejo?
... in just about four beats. Try listening again for "en la". If you don't hear it, don't stress out about it. Just move on and keep learning.
