Meeting women while on the job?

I manage a movie theatre. Because of the hours I work, work is the main place where I have an opportunity to meet women. However, I have always taken a very strick line of not "hitting" on women while I'm on the job. I feel it would be inappropriate, as well as potentially making them feel uncomfortable about coming to the theatre.

What I'm wondering is if there is anything I can do that might encourage women to contact me, or otherwise make the first move after meeting me at work. As I said, work is the main place where I come in contact with women. But most of my interactions with them are strictly as a cashier, or occasionally in a managerial capacity. I don't normally wear a name tag at work, but would this make a difference?
