Tipping's twists and turns

Question: My wife and I dined at a restaurant in Los Angeles where the menu noted that it pays a living wage — about a 15% surcharge. But I was unsure how much to tip. Without the living wage, I would have tipped my usual amount. I favor the custom in most countries we visit, where there is no tipping but the staff is adequately paid and has benefits such as health insurance.
