You have to get combos if you want to get over "Expert" score.

Here's a little trick you can do when those business women (or any of the others) get mad in lineup:
- go to the podium
- mouseover the disgruntled customers
- click and hold down on them as if you were going to seat them
- wait until the podium fills up
- let go of the mouse to drop the customer back in line.
If you were successful your mad customer would have more hearts. I like to do this when there is two or less hearts left on the customer.

You can go search for other Diner Dash threads for more hints.
