What Would Jenna Do?

Dear Jenna:

I'm a 21 year old junior who's at a Georgetown bar at 1:00 a.m. when a drunken Congressman, a married Republican with 3 kids, accosts me and tries to buy me a drink. He's older, balding and represents New Jersey. He gives me a congressional pin but then demands its return, and sends an aide to grab the pin from my chest.

In these circumstances, Jenna, what drink would you order?
