Arrived 10:00am, got through the documents check and filled out overstay warning papers at a waiting area outside the extensions office, then was given a queue number. Waited about 15 minutes went inside sat down. Two male IO were doing paperwork checks again and the passport stamping - bank letter and I had a 3 month statement. He flipped through everything very quickly, no questions asked, had to sign them and add my mobile number on one, Two women were at computers handed PP to them, photo was next and waited for the 1900 baht receipt and told to bring it tomorrow and pick up passport. Did not need a map drawn ( had one with me ) or a photo of yourself in front of your dwelling. Did a TM30 6 weeks prior. Very relaxed IO's, that was an easy 50 minutes !!
