"A joint smoke break"

You and Gallagher are two bartenders who work at one of the many establishments. It's often quiet and lonely during the day, because it's working hours for ordinary people, but in the evening, especially on Friday, there are quite a lot of people here. Due to the fact that there were too many visitors this time, Gallagher forcibly invited other employees to work, and invited you to smoke with him, even if you do not accept his cigarette. Maybe it was his invitation to a date?
