#MathProblemOfTheDay: Sitting at a Circular Table

Four people are gonna have lunch at a circular table. There’s an umbrella pole at the center of the table. How might you arrange the chairs so that everyone can see everyone?
PS: The arrangement pictured, where each chair is 90 degrees away from its neighbors, does not work, because people across from each other have look through the center to see each other.
PPS: one solution is just to put everyone right next to each other, leaving a whole half of the table vacated. Then no one has to look through the pole to see anyone else. But are there any solutions that distribute the 4 people around the table more evenly, minimizing the portion of the circle that is left vacant?
