While yes, there are a ton of things you DO know about In-N-Out (like Animal Style, or how there are Bible passages at the bottom of your cup, or how it's way better than Five Guys or Shake Shack), there are even more you DON'T. As proof, here are 13 things you didn't know about Southern California's burger holy land (with some help from Stacy Perman, author of In-N-Out Burger: A Behind-the-Counter Look at the Fast-Food Chain That Breaks All the Rules).
What to Do at Your Super Bowl Party If You Don't Like Football
1. In-N-Out Burger was founded by Harry Snyder and his wife, Ester, in 1948
The original Baldwin Park location is credited with being the first-ever drive-thru restaurant (take that, McDonalds!). The couple couldn't afford the real estate necessary to have a parking lot for the carhops (which were standard in those days), so they went with the speaker-equipped drive-thru and a name that captured the easy in/out of using it.
2. Religion wasn't a part of the early life of the company
The Bible verses didn't come into play until the 1980s, when Snyder's son, Rich, a born-again Christian, took over the business, making things slightly awkward for hamburger-loving heathens. Making things all-the-way awkward, though? The radio spot that aired around that time, which equated eating In-N-Out with finding Jesus.
3. Managers working for In-N-Out make over $100k a year
They also have full dental and medical, and get bonuses like paid-for trips with their spouses.
4. They don't just sell T-shirts
At most In-N-Outs, you can get tees or free paper hats, but at both the original in Baldwin Park and their company store online, you can also get notepads, folding chairs, windbreakers, and even a woman's bikini (shockingly not available in plus-sizes).
9. In-N-Out's current president is one of the world's youngest female billionaires
She's the granddaughter of the original founders, and lived for many years in secrecy -- mostly because she survived two kidnapping attempts when she was younger. She also went to a private school founded by her family, specifically to give her the education they believed she deserved.
