yes. I had their list of requirements that I picked up at least a month in advance. Then went there with all my documents. A lady reviewed them and then gave me an appointment for the following week. Not mentioning any of the "missing" documents.
When I went for my appointment they required at least 3 or 4 more documents that were not on the list and not required by any other office I've used for previous extensions. One was a document they wanted from my landlord, who did not want to give them it. He is Thai and has a couple dozen rentals and has never needed to supply it before. He was quite upset and even called immigration to complain. So it took running around to a few different government agencies to get documents they would accept instead. Plus another 2-3 trips to immigration.
