WE are always seeking to impart little tips that would make life around our teeming metropolis that much easier. So Keeping Posted has this to offer to those poor souls who queue up night after night, sometimes up to 45 minutes, to taste the fare at Planet Hollywood - the hamburger joint along Canton Road where the french fries come spiced with Tinseltown hype. According to information coming our way, the fastest way to get a table is by shaking the hand - Masonic-style - of one of the staff at the door while pressing a currency note to his palm. Those following this ritual have found tables materialising from between three minutes to 10 minutes - the speed depending, of course, on the colour of the note that has been imparted. One other helpful hint. This ruse only appears to work with the gweilo staff.
