Do not table-hop in clubs. Never go to strange tables and ask women you do not know to dance. You may get a smack on the kisser. But, if you don't, you may be bounced out. It is against the law for night clubs to permit people to mix from table to table. Besides, it's corny, which is worse than illegal.
Gals should not straighten the seams of their stockings in the middle of the dance-floor. There are easier ways to attract attention to the gams.
When entering a night club, don't head for the powder-room before the captain has shown you to your table, otherwise your escort has to stand in the crowded lobby waiting for you and looking foolish (while you take the usual 45 minutes!).
When the lady says she has to go, it is customary to give her four bits for the pro in the powder-room. Which reminds us of the tale about the gal whose nose got shiny eight or ten times, night after night, at great cost to her John. After five years, she walked out on him and bought an apartment house in the Bronx.
Warning: Most night clubs have phone booths in the ladies' room. That's where they call the guy they meet after they brush you off.
