IT might be billed as fast food, but Domino's Pizza company in America yesterday scrapped its 30-minute delivery guarantee, saying half-an-hour wasn't enough to deliver a safe pizza. And it looks as if Hong Kong's pizza eaters might get the thin end of the wedge, and lose their $10 reduction for late deliveries, if the ban is extended worldwide. The company made the decision after a jury in St Louis awarded a woman US$78 million (HK$602.5 million) in punitive damages. She said she had suffered chronic headaches and back pain after a speedy delivery driver from Domino's made her fall over. They were also responding to a number of pizza-connected road deaths throughout the US and the lobbying of one of those public interest groups that inevitably mushroom in America, called People Against Dangerous Delivery. The lobby group claimed that: ''The facts demonstrate, beyond any reasonable doubt, that both Domino's drivers and the general public were endangered continuously and needlessly as a result of the guaranteed delivery policy.'' The news fell rather flat with Hong Kong general manager David Wong, who hadn't yet been officially notified by the US head office that the guarantee was to be pulled. He said Domino's knocked the spots off most of the competition, and that hundreds of pizzas were whizzed around Hong Kong every day by the team of 140 intrepid scooter-riders, for whom the stairs of apartment blocks without lifts were a bigger hazard than the streets. ''We have had no major accidents in Hong Kong, and just a very few scrapes and scratches,'' he said. ''It's different here: we use scooters that can't go more than 50 kilometres an hour - and most of the customers are only about five minutes away anyway.'' He said if it took more than 25 minutes to get the pizza ready for delivery, they automatically stamped it late to stop the driver killing himself - or anyone else.
