In-N-Out attracts attention for its passionate — some say cult-like — following and, because of its immense popularity, traffic jams.

But company president Lynsi Snyder and husband Sean Ellingson wanted the hamburger eatery’s mission statement to include a different type of traffic — and Slave 2 Nothing Foundation was created in 2016.

Slave 2 Nothing “helps those enslaved by human trafficking and/or substance abuse,” said Denny Warnick, vice president of operations.

Every specified donation to Slave 2 Nothing goes directly to supporting a non-profit organization that is fighting human trafficking and substance abuse. Any non-specified donations are divided evenly between the two causes.

Through January (National Human Trafficking Awareness Month), and again in October (National Substance Abuse Awareness Month), In-N-Out will match patron donations 3 to 1 — made either at any of their restaurants or online — up to $250,000, including the new Vallejo site on Admiral Callaghan Lane.

Also, noted Warnick, the In-N-Out Burger Foundation contributes to a third cause, supporting the prevention of child abuse.

In-N-Out covers administrative costs of each fund-raising project, “which means 100 percent of every penny raised, combined with the matching funds contributed by In-N-Out, goes directly to the nonprofit organizations that we support in the communities where we do business,” Warnick said, adding that $3 million has been raised since Slave 2 Nothing’s inception.

“It is our hope that in partnering with our customers and donors, we can help the fight toward ending these issues which affect cities and towns in all 50 states,” Warnick said.

Solano County Supervisor Erin Hannigan said she became aware of Slave 2 Nothing during a visit to an In-N-Out in Auburn “and was pleasantly surprised.”

“In fact I asked and received copies of the flyers from their staff to bring home,” Hannigan said. “I think it’s good because In-N-Out is popular, inexpensive and visible and the awareness would assist in combating human trafficking and it also lets victims know there is help for them. I love that In-N-Out is on board with this.”

Vallejo City Councilmember Katy Miessner also praised the restaurant.

“I think it’s a wonderful cause,” Miessner said. “I’m hoping In-N-Out with their high profile can bring attention to this critical issue.”

Human trafficking is a $32 billion a year business with a 35.7 percent rise in reported cases in America from 2015-2016, according to the In-N-Out web site with 44 percent polled human trafficking survivors indicating they were 17 or younger.
