What do I need to know about doing a border run at Chong Chom from Prasat, Surin?

A user is seeking advice on doing a border run from Prasat, Surin to Chong Chom, their nearest border crossing to Cambodia. They inquire about whether it's necessary to stay one or two days in Cambodia, as they currently do not have a car and prefer not to extend their visa in Surin. Comments from other users suggest that the experience at Chong Chom can be swift, sometimes taking as little as 20 minutes, especially if you use a local service to expedite the process. However, travelers are warned that re-entry into Thailand can be unpredictable, especially with multiple entries logged.
