8. Bother a celebrity for a photo/ autograph if they're talking to a friend/ having dinner/ doing something "normal people do"
Unless it's at The Grove. Then they're just asking for it.
9. Drive drunk
Ever. For any reason. Uber, Sidecar, Lyft, and taxis all exist so that 1) you don't kill anyone, and 2) you don't spend $10,000 you don't have to clean up a mess that didn't need to happen, at all.
