A restaurant owner in the village of Abu Ghosh, just outside Jerusalem, offered a 50-percent discount for patrons who turned off their cell phones. Jawdat Ibrahim believes that smartphones have shifted the focus of meals from companionship and conversation to surfing, texting, and business calls. “Technology is very good,” Ibrahim says. “But . . . when you are with your family and your friends, you can just wait for half an hour and enjoy the food and enjoy the company.”
