Anyone can come regardless of their identity. The only exception is that Lai doesn't want people to come to "gawk" with the same mindset they would have if they were visiting a zoo. That is why he is like a mother hen, protecting his "comrades" from having their identities exposed.
其實這裡只是較多同志出入，並沒有特別限定對象，想來的人，不管是什麼身份的人都可以來；只是，賴杞豐不喜歡別人抱著「參觀動物園」的心態前來「獵奇」，所以他總是必須像老母雞一樣，保護同志，避免他們的身份曝光。
