These Charming People by Michael Arlen

Now it happened that one night, not long ago, Shelmerdene, having nothing better to do, rang me up and, complaining thus and thus, suggested that I should do the manly thing and dine with her. It was such a rare happening that I remember it all vividly. I remember I adopted an offended attitude, asking her if she thought I was the kind of man who was so lacking in dinner engagements that I could be rung up to take a lady out to dinner at the last moment. I asked her who she thought I was. I asked her to dine at the Ritz. But then, after a certain amount of talk this way and that way, we decided that we would be frightfully gay, and so we went to dine at the Ambassadors.

Of course, you know the Ambassadors. Every one knows the Ambassadors. Every one has passed through its mean but patrician-looking entrance in Bond Street, just between a jeweller's and a fishmonger's. It is, of course, a Night-Club, though there is nothing to prevent you going there in the afternoon if you feel that way. It is an exclusive Night-Club. Outside it are posted tall men in brilliant uniforms adorned with medals, and these men have the eyes of hawks, for it is their business to sift out the low and vulgar from the fashionable crowds that perpetually strive for admittance; they are the best sifters of their kind; and on any night of the week you will see at the Ambassadors all the quality and only the quality, toying with their food and calling each other by their Christian names.
