I feel like people who are considered “attractive” have an advantage whether they “use it” or not. If you look a certain way, and someone does you a favor because of that, it’s not necessarily because you tried to get them to.
For example, I was at an on-campus bar the other day looking all dolled up, and wearing make-up and a dress for once. I was sitting outside with my friends, and I had left my car in 15 minute parking for quite a while longer than that. When the traffic cop came by, I went over to move my car, and before i could, he said something to the effect of not to move it now but he would be back in about 30 minutes, and it better not be there then. When i went back to my friends (quite pleased with the situation) all my friends, who happen to be male, and who hang out there a lot more often than i do, told me how lucky i was, and that if it was them, he wouldn’t have let them off so easy. they would have probably gotten a ticket.
i didn’t try to use the way i looked to my advantage, but it seemed that it worked to my advantage anyway.
