"Does that mean that I'm useless as a VIP customer?" Han Junting asked.
Assistant Manager Zhuo said evenly, "Miss Han, we're simply doing things according to the rules. After all, Miss Su made a reservation first. Our restaurant's rule is that a guest's reservation is given priority. Of course, as a VIP customer, you'll also be given priority. Thus, we have already prepared a private lounge area for you to drink coffee. You can rest for a while and wait for a vacancy."
In other words, if Han Junting had made a reservation, this private room might have been hers. However, she felt that she was of noble status and didn't have that kind of self-awareness. She felt that if she came at any time, the restaurant should prepare a private room for her.
If they didn't do so, it would be an act of disrespect against her. The restaurant was expected to ignore other guests to welcome her.
