Hugs

Have hugs gone mainstream? Are they now the North American version of the European kiss? The past couple of weeks I've met three different guys for "dates" and two out of the three expected a hug at the good bye stage. Is this the new normal? I don't recall hugs being a normal greeting for two people who are not closely acquainted with each other. Obviously, I hug the people close to me when I see them and when I say good bye. But a stranger? No thanks!
