As long as you don’t need to work, you must not go to such places.

I’m 16 and still live at home, so I don’t need a job to survive. But I would need one to get experience which could be useful in the future and also to make some extra money. Unfortunately 99% of the jobs in my country are mixed, is it permissible if I get a job at a place that is mixed? What about if the women are older and I limit interaction?
