Playing a U.S. Open course for the first time is like going to a wedding of a good friend. Follow all the protocol, appear confident, keep your foot out of your mouth, and you might end up with a couple of dates with a not so bad looking college roommate of the bride.
Playing an Open Championship links course for the first time is a different kettle of fish. Likely you crash and burn, find yourself sulking alone after midnight on the curb in the parking lot. But, if you concentrate really hard, artfully choose your words, and catch a couple of lucky breaks you may just end up in the morning having had a memorable adult experience with what seemed like a rather plain faced girl with a kinetic smile.
