http://en.wikipedia.org/wiki/In-N-Out_Burger

Summary:

Opened in 1948 in Baldwin Park, CA and was the first drive through hamburger stand. Privately owned and headquartered in Irvine, CA, is run by heirs of the founders Harry and Esther Snyder. Now over 18,000 staff at more than 290 locations in California and Southwest. History of trashy family feud lawsuits. Favored by celebrity chefs.  Paper cups used at restaurants feature discrete references to bible verses.

Oh, and, the current owner of the company is heir Lynsi (note spelling) Torres, who is listed by Bloomberg as the youngest female billionaire in the US. She was born in Glendora, California to Lynda Lou (née Perkins) and Harry Guy Snyder.  At age 12, she moved with her parents to the small city of Shingletown, California, where she graduated from a private Christian high school and lived on a ranch. Her parents divorced in January 1997, when she was fourteen. She has two older half-sisters (Traci and Teri) through her mother. Traci is married to former In-N-Out President and current COO Mark Taylor.
