What does KTV mean by smoking for female colleagues?

Smoking is a kind of respect for you, because in fact, in the traditional etiquette of China, when others meet you, whether they know you or not, then others will smoke for you, which is a friendly attitude towards you.

It's a matter of courtesy. Usually when we meet, we will give cigarettes to show respect. Usually at weddings or banquets, I will also give you cigarettes. This is a kind of respect and attention to the guests. This is a way of interpersonal communication. There is no other special meaning, don't think too much.
