The Consumer Council yesterday voiced its concerns over Sunday's chaotic scenes when thousands of people pushed and elbowed each other while queueing for a special offer on mahjong sets in Wan Chai. The council said companies should make appropriate arrangements when launching such promotional drives to avoid causing 'chaotic situations'. Police struggled to control 5,000 people in wet conditions as they surged across slippery Harbour Park Road to the China Resources Building to snap up the offer from Blue Girl Beer. Three women were injured and children were separated from parents during the chaos. 'The traders, hopefully, would not cause such chaos. [They should] make an adequate number of goods available and have good arrangements so the public can get them calmly,' the head of the council's complaints and advice division, Chan Wing-kai, said. Mr Chan said there had been no complaints concerning Sunday's incident. The council had also urged the public to think carefully before taking up the promotional offers. Twelve beer caps and $108 were needed to retrieve a set of fake crystal tiles that are available for less on the mainland. 'The consumers should consider whether they need the goods on offer and not take the offers regardless,' Mr Chan said. 'They should also consider whether the offer is good value. 'As you can see from reports yesterday, the mahjong sets were actually sold cheaper on the mainland.' The public should assess the situation before queuing and avoid taking children or the elderly along if possible, the council added. Sunday's chaos was not the first time concerns had been raised about similar promotion activities, the council said. It was aware of nine incidents where thousands of consumers were involved. The complaints mostly concerned unsatisfactory goods and poor arrangements for their distribution. Despite the pushing and shoving, by the end of Sunday night there were still more than 1,000 mahjong sets left, and the organisers pulled the plug on the promotion and decided they would not make the remaining sets available to the public.
