When the server first comes over we usually politely let them know that we'll be needing our check split. Sometimes it's easier for them to know this ahead of time, especially if they have older POS terminals. I've also found that individually we tend to tip 20-30% but when there's a large check that has to be paid on one card (with cash and IOU's going to the card holder) the tip tends to be <20%.
