Absolutely anything is possible here. Study the system, bust a move. I had a bank account and bought a brand new motorcycle in my own name on a tourist visa. Not going to happen if you're starting at 1000 thb. Get your numbers noticeable and you'll see results
Before Nong Bua had an office I used Udon Thani also. Same as you, I was treated nicely and they sometimes filled out paperwork as well. Generally Thai govt officials do as they are treated. Respect earns respect
