In large social settings(bars, clubs) where I haven't yet isolated a one on one, but shes only talking to me and giving out IOIs, I've noticed I have a problem being interrupted by other multiple guys in groups attracted to the girl in talking to. I'm normally a calm and easygoing guy and that's how I've built my frame around having fun. How do any of you deal with the situations and how do you refocus the conversation back to wards getting back to a 1on1 convo?

I know how to be the loudest person in the room but I'm asking for help with interruptions once I've settled the energy down to a personal conversation.
