From todays Bangkok Post:
Bangkok Post : Sohpon acts to prevent airport scams
Pretty swift action but not surprising given the precarious state of the tourist industry here.
All airport 'duty free' is a scam anyway. It would help if there was more competition for King Power, who hold the monopoly at Suvarnabhumi. If the embassies recommended that their citizens use the down town emporiums (Siam Paragon and the like) then they would get a much better deal and no worries about being falsly accused of shop lifting.
