A VIGNETTE of life among the yuplets: Matthew Marsh of Triton Telecom Hongkong is in the tele-media business. That means he spends his day finding new uses for telephone lines. In a moment of kind-heartedness, he arranged for his amah, whose name is Tet, to have her own phone in their flat in Wang Fung Terrace, Tai Hang Road. He then got into the habit of phoning her from his bedside telephone every morning when he woke. ''Good morning, Tet, I'd like some Frosties and a cup of tea,'' he'd say. It was like having room service. On Monday night a group of them went out for a late night in Wan Chai, to celebrate a visit by Triton's London-based chairman, Patrick Naughton. Result: Matthew was in a semi-comatose state with a serious hangover yesterday morning. His flatmate, Peter Grimes of Quotron, was in a similar condition. Although Peter's room is a mere 48 inches from Tet's domain, he did not have the strength to crawl that distance. So he used his mobile phone to call his flatmate Matthew. Matthew put Peter on ''call waiting'' and phoned Tet's room to order an urgent bulk delivery of caffeine for the two of them. In other words, the request went from Peter's room to the mobile phone exchange downtown to Matthew's room to the Hongkong Telephone exchange in Causeway Bay to Tet's room, 48 inches away from where it started. Just thought we would record this story to show how new technology is being employed for important uses. Brolly good idea READER Shona Parker asked yesterday: ''I'm dying to know. Who was the person I saw on Sunday driving his open top sports car into the Government apartments at Leighton Hill? ''It was raining cats and dogs but he had solved the problem by pinching one of those huge table umbrellas, most probably from the nearby football club, and propping it up inside the car. ''He could barely see out through all the cigarette advertising.'' If he stole a few patio chairs too and strewed them around the car he would have a mobile garden party. Futures shock FUTURES traders gaped yesterday afternoon as a troupe of beautiful bodies marched onto their trading floor in Citibank Plaza. The hunky men and lissome ladies then started to do aerobics in the hallowed hall, formerly used only for reducing the girth of bank accounts. The traders did not exactly leap to join in, but ''a few people waved their arms about a bit,'' said Miss Futures 1993 Virginia Mumford. But what was it about? Had a class from Tom Turk's (elsewhere in the same building) gone astray? No. It turned out to be a Government promotion called International Challenge Day, designed to inspire people to do 15 minutes' exercise every day. Actually, the futures staff are already a pretty lean and mean bunch, not like your overweight stockbrokers. Futures trading consists of putting on your team colours, storming onto the trading floor, elbowing rivals out of the way, waving bits of paper and screaming passionately. It's a bit like how Legco should be. Death Row THE Joe the Camel cigarette advertisement is not only on the corner of Stubbs Road, but is just yards from the heart and lung health centre, Ruttonjee Sanitorium, commented Jeff Hagan of SBCM yesterday. Just behind the Sikh Temple is the AIA Building, which has coffin-shaped windows and houses a leading life insurance company, added Dr John Ma of Pedder Street. That whole area seems to be a package deal. Meanwhile, we reckon anti-smoking campaigner Dr Ronald Leung Ding-bong is doing no one any favours by telling the Government that since it is making money for taxpayers by selling confiscated cigarettes, it might just as well sell heroin and cocaine. Don't put ideas into their heads, Ronald. No comeback RICHARD Parry of the Regal Riverside Hotel was in Guangzhou last week and picked up a copy of that essential magazine Guangzhou Today. In it he found a rather backhanded compliment about the Yuexie District, in the shape of the following slogan: ''People may enjoy themselves in these places so much as to forget to return.'' Hmm. That's what we call putting a positive spin on things.
