Though it's more difficult to get rid of them at night, it can be done if you and your pal are halfway intelligent. You will want to load them up with tickets for all the highbrow shows, the opera and concerts, and pull the oldie about "Hon, you know I'll fall asleep if I sit through that." Or you can tell 'em you and the pal have an important business date and will meet them at the hotel later. But if you are here with your old lady and have no one to park her with, you are in trouble. You can find some free daylight time, naturally, by bundling her off to the shops or the hairdresser's, or alibiing with business. But, we ask you, what are you going to do with yourself in the daytime? New York is strictly an owl town. You might take a dance lesson at one of the numerous Arthur Murray branches or sit in a lobby and try your luck at ogling the dolls or kibitz with the manicurist, but none of these are exciting and they can be done better in your home town. You know your wife better than we do, but if you can't check her in a theatre by herself at night, or if you have no relatives in town to leave her with, you are out of luck. * * * * * Married ladies will not need our professional advice on ducking husbands. They know how. And husbands rarely refuse. For the married couples who do want to make our town together, but are handicapped by children, dogs or canaries, ask the bellboy for services that mind infants, walk dogs and sit up with older children. * * * * * MIDNIGHT MANNERS: Don't bring children to night clubs unless it's someone else's precocious daughter. Visitors, who have no other place to leave them, are the worst offenders. Cabarets are not for schoolkids--even at the early dinner shows. II If you haven't a date, get one. Call the bellboy or refer to Chapter 33 for friendship services. * * * * * (INSIDE STUFF: When a guy calls for you in a limousine or private car bearing a license number in the 82 series, it's rented. Hirers of rented limousines may be phonies or wise guys. If you want to make believe, there's no better way of putting on the dog than engaging a Carey Car--a brand new Cadillac limousine with uniformed chauffeur, rate $5 an hour, less over considerable periods. Many legitimate people also use these rented cars, sometimes hiring them by the month or year. They get 24-hour chauffeur service, perfectly conditioned cars, and thus eliminate garage, repair and insurance worries. Other wise guys use these cars to go to the theatre, airport or outside the city limits. The fee is only slightly more than a cab, and cars are always available by phone. It saves time and trouble of waiting and whistling for cabs and arguing with drivers.) * * * * *
