There are a few that guys use pretty regularly (at least the guys I was chatting with). Here are three:
The Reach Test: If she reaches for her wallet when the check comes. Though most guys will pick up the bill (especially in the beginning), they still like the idea that their date is willing to pay. “It shows she’s considerate,” my friend says.
The Party Test: How she interacts in a social setting. If a woman is able to hold her own and mingle with his friends/family without his constant attention, it’s a major plus. That’s not to say your guy should abandon you when he brings you to a social gathering, but he shouldn’t feel the need to babysit you the entire time either.
