I had the same Prob when I first arrived! My wife (and ALL Family) said "Dont need" )..... Eventually, we did it together at Chaeng Wattana . Now I do mine online (TM30online) and print a copy for Reference. Need a new one each time we return from overseas Holiday. Takes a couple of minutes. Good Luck.
