HAVE you ever thought of enjoying a day on the beach with friends inside a cosy beach hut? Over at South Bay three bathing sheds will be available for daily hire, starting from tomorrow, on a 10-week trial scheme. The sheds are built in the shade of trees, have an electricity supply, and are equipped with simple garden furniture and fans. Each shed can accommodate up to 10 people, and can be rented at $150 a day, from 9 am to 6 pm. Besides having fun in the sea and on the beach, you may also make use of the nearby barbecue facilities and buy snacks and refreshments from a food kiosk nearby on the beach. You can make your bookings 14 days in advance at any of the 60 or more booking offices of the Urban Council's recreation venues. On-the-spot bookings can be made at the Urban Services Department office at South Bay Beach if huts have not been previously booked. For more information, you should call 2812-9715 or 2555-9027. The Auxiliary Medical Service (AMS) is introducing a new hotline to mark its 45th anniversary. Starting tomorrow, the 24-hour hotline - 2762-2033 - will offer members of the public basic information about the AMS, including services provided, enrolment procedures, training and welfare. The service also gives information about first-aid treatment for accidents and emergencies. You can learn how to handle cases of trauma and bleeding, asphyxia, unconsciousness, fracture, burns, scalds, head injuries, poisoning and shock. You can either listen to recorded information on the hotline or get written information by fax.
