Ahh the risks...
If you pick the hottest in the room. She may be tired of being too busy.
If you pick the one who makes eye contact, she may be desperate for money, or she may genuinely want you
If you pick the ugly one who you think can service you better then what happens if shes terrible? You get the worst of both worlds.
I would personally pick the hottest and roll the dice, if shes terrible atleast you can help yourself across the line
