For instance, I'm having a local restaurant make Thanksgiving dinner, and I would like to place my order and probably ask some questions. When is the least busy time to call a restaurant? My first thought was mid-morning, because they would be open probably around 10 and they wouldn't have anybody for lunch yet. But, then I thought that's probably one of the busiest times b/c they're prepping for lunch. While this is a specific situation, I've often wondered this when I call to ask for a reservation. Opinions?
