Can we do a border run after entering Thailand with a 30-day visa for another 30 days?

The original concern is whether a border run after entering Thailand with a visa exempt category will grant another 30 days upon re-entry. It’s confirmed that you can get a 30-day extension at a local immigration office on each entry. However, there are limitations: only two land border entries are allowed within a calendar year under visa exemption rules, while air entries can be unlimited unless denied by immigration. Moreover, if needed, applying for a 30-day extension in Thailand is an option, which might be more feasible than making border runs.
