The Royal Thai Embassy in Singapore was incredibly user friendly and efficient. The drop off of documents took me literally three minutes from the moment I walked to in to when I left. The staff is very friendly, no questions asked or more documents requested.
The visa pick up was the next day between 2:00 and 3:00pm, you also walk in and out within minutes.
(Just in case this is useful information for anyone)
