Quotation from: The Efficiency Expert

Written by: Edgar Rice Burroughs

Christmas Eve at Feinheimer's is, or was, a riot of unconfined hilarity,
although the code of ethics of the place was on a higher plane than that
which governed the Christmas Eve and New Year's Eve patrons of so-called
respectable restaurants, where a woman is not safe from insult even
though she be properly escorted, while in Feinheimer's a woman with an
escort was studiously avoided by the other celebrators unless she chose
to join with them. As there was only one class of women who came to
Feinheimer's at night without escort, the male habitues had no
difficulty in determining who they might approach and who they might
not.
