Do you need customs guarantee when traveling from the Philippines to Thailand? Who exactly needs this guarantee?

To be honest, ever since the visa exemption was extended to two months, the demand for customs guarantee services has significantly decreased. I am based in Thailand. Recently, many people have been asking me about customs guarantee services, and I've grown quite impatient with these inquiries. I'm sharing this information publicly, please remove my username to avoid accusations of soliciting traffic. Moreover, the maximum charge for customs guarantee is 2,000 Thai Baht, which is the standard market rate.
