We submitted the documents yesterday at the same embassy as you. They asked for a statement for 3 months. The only thing that worries me is that we had a large transfer to the account 1 week ago, which was 500k THB. But they didn't tell us anything. They accepted the documents and payment. We'll find out tomorrow.
We also applied in Laos. Could you share with us while you were waiting for 2 days, did they call you or ask for additional documents? People say they do this often in different Embassy. We are worried that they do not ask for anything. For Thais, this is more likely a refusal.
