Thursday Think Tank

1 Chief Executive Donald Tsang Yam-kuen to take control of battle against youth drug use ... that's because Chief Secretary Henry Tang Ying-yen is too busy fighting on the dangerous tree front.

2 Plastic bag levy comes into effect ... but some confused people now think you can't use them indoors at bars, karaoke clubs and mahjong parlours.

3 Public libraries short of HK$21 million in unpaid fines ... just what the economy needs - more bad loans and poor bookkeeping.

4 Government approves five more horse racing days ... like domestic maids, horses don't need minimum work hours.

5 New three-tier ambulance dispatch system will respond in nine, 12 or 20 minutes ... in other words, for real emergencies, take a cab. It's faster.'
