Beat me to it! They run this country with a " different courses , different horses" type of attitude - often totally illogical. Not wanting to go off topic, but take for instance, the ludicrous situation at Immigration Offices throughout the country where the interpretation of the rules and regs are down to the particular Immigration Officer involved in the case.
And in this instance, if it's OK for Phuket, why not for other tourist areas like Pattaya, Koh Samui. Hua Hin etc,?
