YOU SAID:
You know how to take the reservation, you just don't know how to hold the reservation. And that's really the most important part.
INTO JAPANESE
予約を取る方法を知って、予約を保持する方法は知らない。本当に最も重要な部分であります。
BACK INTO ENGLISH
You don't know how to know how to take the reservation, to hold the reservation. Is really the most important part.
INTO JAPANESE
予約を保持するために、予約を取る方法を知っている方法を知っているしないでください。実際には最も重要な部分です。
That didn't even make that much sense in English.
