Well NO-ONE ever has to show banked money on entry.
People only ever have to show banked money when applying for visas and when applying for extensions.
The consulate you used only wanted to see $700. The norm is wanting to see 400,000 baht (which matches up with the requirement to get an in-country one-year extension). One that I heard of wants to see 400,000 baht PLUS 40,000 baht per month income). That's to get a 90-day O-visa.
