INSIDE STUFF: Many smaller night clubs, especially those on side streets and in Greenwich Village, cheat. Some headwaiters have been known to introduce strangers for a stiff tip. But if you sit out with the tramps in these places, count your drinks, watch your check--and better check your watch. * * * * * BEWARE of steerers. If a stranger in the street or hotel lobby or a cab driver asks you if you want to meet a gal, shake your head hard. Odds are he is a runner for a clip joint. * * * * * WISDOM OF A WHITE WAY WOLF: Don't date a late-dater unless you are her late date. (Late-dater: a doll who ducks out on her dinner date at midnight to meet another guy--usually a musician.) Three funny gags that make 'em laugh are worth more than three hours of romantic salesmanship. Get yourself a big, fierce-looking hound and walk him around the block. Not only is there a free-masonry between all pooch-lovers, male and female ... but plenty of soft little cuties will stop to admire the brute. Then.... Most girls are now too smart for the "ya oughta be in pichures" hokum, but no doll can stand off a guy who "breaks her down." Insults far oftener than flattery bust barriers on Broadway. Never trust a gal any farther than you can throw a trap-drummer. Common courtesy demands that if your doll airs you, she rates one day to return. (Unless you have to catch a train home that day--then give her two hours.) If she doesn't show up, find a stand-in. Census bureau says there will be 750,000 more does than stags in this postwar world. When you take a likely candidate to the Stork or El Morocco, don't try to impress her with your friendship with big shots by introducing her to a movie star or millionaire playboy. She'll probably end up with him--instead of you. But if she rhapsodizes about a good-looking guy or celeb at another table, go and bring him over and tell him in front of her that your little friend goes for him. She'll be terribly embarrassed. (_Confessions of a Cautious Cutie_: Yes, but she'll slip him her phone number, too.) If you get your dates mixed up and end up with two Little Red Riding Hoods on the same party, don't explain. Smile in a superior way and let the pigeons fight over you--not you over them. Never enthuse to a fellow wolf about your latest conquest--unless you're trying to lose her. If you are with a new pretty, tip the headwaiter NOT to give you a ringside table in full view of the other wolves. Do not let her dance with your pals. Let them dig their own. Be a good fellow, but not that good. Don't introduce her at all if you can get out of it. Never pan your pal to your doll and surely don't tell her he's a bad egg with women or a quick-change lover. If you do, you'll find your femme so interested, she'll turn flipflops for him.
