Diner Dash - Platform: iPhone Customer cannot leave: ---------------------- If customers are at 1 heart level and your podium heart will not hold them long enough, then move the pointer over the customer and "hold" them until your podium heart is full. The customer will not be able to leave. Efficient service: ------------------ If your table is full and there are three or more packs of guests, click the table that is ready and go to the podium. Serve the food then go to the podium. Repeat the move until the table is empty. More money: ----------- If you are on the second restaurant and your customers are at full hearts, give them more beverages. They will pay you more money than normal.
