The Doctor's Dilemma by George Bernard Shaw

After dinner on the terrace at the Star and Garter, Richmond. Cloudless summer night; nothing disturbs the stillness except from time to time the long trajectory of a distant train and the measured clucking of oars coming up from the Thames in the valley below. The dinner is over; and three of the eight chairs are empty. Sir Patrick, with his back to the view, is at the head of the square table with Ridgeon. The two chairs opposite them are empty. On their right come, first, a vacant chair, and then one very fully occupied by B. B., who basks blissfully in the moonbeams. On their left, Schutzmacher and Walpole. The entrance to the hotel is on their right, behind B. B. The five men are silently enjoying their coffee and cigarets, full of food, and not altogether void of wine.

Mrs Dubedat, wrapped up for departure, comes in. They rise, except Sir Patrick; but she takes one of the vacant places at the foot of the table, next B. B.; and they sit down again.
