Even service jobs occasionally give paid lunch hours. When salaried, the whole point is you don't need to track hours. Otherwise you need to bill for that 5 minutes of insight in the shower on Sunday when you have an idea that solves some important business problem. Anyway since I'm generally thinking about work related problems during lunch, frequently even eating at my desk, and lunch rarely takes a full hour, I've always considered my "lunch hour" as part of the total work day, and never had anyone higher up question it.
