Will a 1.5-hour overstay after my tourist visa expires cause problems at Thai immigration?

The user is concerned about a potential 1.5-hour overstay due to a change in their flight schedule, which is set to depart just after their tourist visa expiration. Community responses indicate that overstaying under 24 hours generally incurs no fines, only a small stamp in the passport. Recommendations include checking in early and clearing customs before midnight on the visa expiration date to avoid any complications.
