My classmates came to see me and stayed in a hotel. I went to see him during the day. Did the staff let me in?

Hello, if it's just a hotel, everyone can enter.

As for going to see other people's works, that's no good. . Although they won't check your papers or kick you out. .

But you can't go in, because you will hinder the work of the staff here. .

But the dormitory is open to everyone. . Because the dormitory is the residence of employees. . It is his freedom to invite anyone in. .

But it's not good for you to enter the boys' dormitory alone. .

Why don't you wait outside and have dinner with him after work or something? .
