A waiter came swiftly along the room, and then stopped dead. His stoppage was as silent as his tread; but all those vague and kindly gentlemen were so used to the utter smoothness of the unseen machinery which surrounded and supported their lives, that a waiter doing anything unexpected was a start and a jar. They felt as you and I would feel if the inanimate world disobeyed-- if a chair ran away from us.

 The waiter stood staring a few seconds, while there deepened on every face at table a strange shame which is wholly the product of our time. It is the combination of modern humanitarianism with the horrible modern abyss between the souls of the rich and poor. A genuine historic aristocrat would have thrown things at the waiter, beginning with empty bottles, and very probably ending with money. A genuine democrat would have asked him, with comrade-like clearness of speech, what the devil he was doing. But these modern plutocrats could not bear a poor man near to them, either as a slave or as a friend. That something had gone wrong with the servants was merely a dull, hot embarrassment. They did not want to be brutal, and they dreaded the need to be benevolent. They wanted the thing, whatever it was, to be over. It was over. The waiter, after standing for some seconds rigid, like a cataleptic, turned round and ran madly out of the room.
