They don't stand in lines or take turns. If you're waiting to order a sandwich and don't act fast enough, someone behind you will scream out an order, elbow her way up to the counter, pay and be through with lunch before you know what happened. Noise is another thing. They blow their car horns and holler at other drivers. They don't talk, they yell.
Every Hebrew conversation sounds like an argument, with voices raised and arms flailing in the air.
Only when they hug at the end do you have a clue that they were discussing whether to have fish or chicken for dinner. A cell phone is to Israelis what a water bottle is to Californians. As for cell phone etiquette, well, there is none. Once I watched a couple in a restaurant talk on their cell phones throughout the entire meal, never exchanging a word until the check came. If you ask an Israeli for directions to a restaurant, he'll suggest a better place to eat or what to order or will tell you to make sure to say hello to his cousin, Yael, who works there.
