THE Keeping Posted hotline took an interesting call yesterday from a resident at Tregunter Towers - the luxury Mid-Levels apartment complex that is now cursed with having to play host to a nauseous racist clique. She told us in hushed tones that she might ''in due course'' be able to name names as to who among the tenants - a minority, we might mercifully add - were responsible for sending out the abhorrent note to the flats telling the Filipino maids that they ''should take the service lift where you belong''. The poisonous missive further advised: ''If you don't like it, please go back to your country. Don't forget that you are employed here as servants!''. If the meagre information we garnered from our caller as to the identity of the perpetrators is correct, then we dutifully suggest that one of the prime movers behind that odious dispatch heeds her own advice to: ''Go back to your country''. For now, the poor maids who toil diligently in the cause of their masters and mistresses at Tregunter can but hope that those responsible for sowing hatred will gradually relent and rejoin the human race. Meanwhile, we eagerly await another call from our ''concerned Tregunter resident''.
