From Porn Star to Waiter: 5 Confessions From Porn Star to Waiter: Top 5 Work Confessions Flight Attendant on Mile-High Club, and Waiter's Revenge on Bad Tippers Aug. 10, 2012 - Porn Star Savanna Samson, Convent Girl "20/20" interviewed workers in five professions, from porn star to HR executive, going behind the curtain to learn the tricks -- and secrets -- of the trade. Here is the top confession from each. Watch the full story on "20/20: True Confessions" Natalie Oliveros is a New York City working mom devoted to her young son. She cooks breakfast for 10-year-old Luchino, takes him to school every morning and even cuts his hair. Oliveros' professional name is Savanna Samson, and she is an adult film star. Her Adult Video News awards for group sex and best all-girl sex stand prominently displayed in her home. As if that weren't enough of a revelation, Oliveros told "20/20" of her not-so-naughty childhood. "I was always so close to God," she said. I stayed a couple weeks at the convent when I was a kid. But I didn't become a nun, because I wanted to have sex. Flight Attendant Mile-High Club According to Heather Poole, a veteran flight attendant and the author of "Cruising Attitude," flight attendants know when passengers are joining the Mile-High Club in the bathroom from the long line that forms. These days, Poole said, if it's an overnight flight you're more likely to find lofty lovers skipping the bathroom altogether. "When one passenger is sitting on top of another passenger, you have a pretty good idea of what might be happening there," Poole said. Throw that blanket away! Human Resources Executive HR People Snoop to Avoid Hiring Working Moms Hiring managers aren't allowed to ask applicants about their personal life, medical condition or age. But Cynthia Shapiro, a former human resources executive who is now an advocate for workers, told "20/20" that clever managers will try to get applicants to volunteer such information themselves. Some put a framed family picture on their desks to encourage interviewees to spontaneously talk about their own kids. One manager would actually follow applicants back to the parking lot to see their cars. They're looking to see what kind of car you drive. They're looking to see if you have a baby seat in the back. Waiter A Waiter's Revenge Chase McGowan, a waiter at an upscale Los Angeles restaurant, told "20/20" of the revenge he took on a couple of bad tippers. It started when they asked him to call them a taxi. I come back, and I say, Your cab's waiting. It's outside, in the back by the Dumpsters. That's where we have people picked up by cabs," McGowan said. The Dumpster smells horrible. It smells like alcohol and rotted food. And I kept looking out the window, watching as these two people waited for a good 20 minutes for a cab that I never called. Delivery/Postal Worker The Holiday Spirit A worker at a post office on New York's Long Island was arrested in 2011 for stealing $40,000 worth of computers and jewelry. The packages they were in never arrived at their destinations, but they did show up on eBay -- leading to the arrest. That was extreme, but petty theft by carriers does happen, according to Ryan Bradford, a former U.S. Postal Service employee. "Old timers would tell you stories of people stealing Netflix DVDs and gift certificates," Bradford told "20/20." Especially around Christmas. Watch the full story on "20/20: True Confessions"
