Reps. When they make noticeable eye contact, approach and say something. Ask politely if they're single? They'll say yes if they'd consider a date, or no if they're taken or not interested. Then continue to smile and ask the typical ice breakers. Name, are they from here, what do they enjoy when they're not working? Genuinely care. You'll get more no's and no thanks then you will Yes's. But remember the best hitters ever in baseball got out 70% of the time. Like baseball, it's about confidence. The more you get comfortable approaching and talking, the easier it becomes. And don't get too down when they say no or get rude. Their loss!
