Can using a concierge service at Bangkok immigration help reduce issues for frequent visa exempt travelers?

Concerns have been raised about potential hassles at Bangkok's immigration for travelers with multiple visa exempt or SETV entries. While using concierge services that offer fast track immigration might seem beneficial, experiences among users vary significantly. Some report being grilled even while using fast lanes, suggesting that the scrutiny may not decrease, and officers may take more time to examine entry histories when the rush is less. There are anecdotal instances where travelers felt more valued and had smoother experiences, yet issues were still reported. The overall sentiment indicates inconsistency based on individual officers and highlights the importance of ensuring all travel documentation is in order. Additionally, recommendations for specific concierge services were requested, linking to searches for fast-track services.
