"Why not?"
"Because—because—those are terms of politeness between—"
Our friend hesitated, and we interrogatively supplied the word, "Equals? There are always difficulties between unequals. But try this, some day, and see what a real gratitude you will get from the waiter. It isn't infallible, but the chances are he will feel that you have treated him like a man, and will do or say something to show his feeling: he will give a twitch to your under-coat when he has helped you on with your top-coat, which will almost pull you over. We have even tried saying 'You are welcome' to a beggar. It's astonishing how they like it. By-the-way, have you the habit of looking at your waiter when he comes to take your order; or do you let him stand facing you, without giving him a glance above the lower button of his poor, greasy waistcoat?"
"No, the theory is that he is part of the mechanism of the establishment."
"That is the theory. But it has its inconveniences. We ourselves used to act upon it, but often, when we found him long in bringing our order, we were at a loss which waiter to ask whether it would be ready some time during the evening; and occasionally we have blown up the wrong waiter, who did not fail to bring us to shame for our error."
"They do look so confoundedly alike," our visitor said, thoughtfully.
"We others look confoundedly alike to them, no doubt. If they studied us as little as we study them, if they ignored us as contemptuously as we do them, upon the theory that we, too, are part of the mechanism, the next man would be as likely as we to get our dinner."
"They are paid to study us," our visitor urged.
"Ah, paid! The intercourse of unequals is a commercial transaction, but when the inferiors propose to make it purely so the superiors object: they want something to boot, something thrown in, some show of respect, some appearance of gratitude. Perhaps those dairymaids did not consider that they were paid to stand up when their employer and the visiting celebrity came into the milk-room, and so, unless they were civilly recognized—we don't say they weren't in this case—they thought they would do some of the ignoring, too. It is surprising how much the superiors think they ought to get for their money from the inferiors in that commercial transaction. For instance, they think they buy the right to call their inferiors by their first names, but they don't think they sell a similar right with regard to themselves. They call them Mary and John, but they would be surprised and hurt if the butler and waitress addressed them as Mary and John. Yet there is no reason for their surprise. Do you remember in that entrancing and edifying comedy of 'Arms and the Man'—Mr. Bernard Shaw's very best, as we think—the wild Bulgarian maid calls the daughter of the house by her Christian name? 'But you mustn't do that,' the mother of the house instructs her. 'Why not?' the girl demands. 'She calls me Louka.'"
"Capital!" our friend agreed. "But, of course, Shaw doesn't mean it."
