Currently, the business and service sectors are widespread, as they are considered integral to all types of businesses. Every business relies on service businesses as tools for operations, from production labor to transportation. Service businesses are often in the form of labor that responds to customers' satisfaction and expectations, with income generated from service fees. The Thailand Professional Qualification Institute (Public Organization) has promoted the development of Occupational Standards and Professional Qualifications for various service businesses, including transportation services, cleaning services, and pet care businesses, which have seen significant market growth each year. Therefore, those involved in the business and service professions must prioritize and pay attention to their clients, as this group of consumers seeks trust, cleanliness, and safety. Additionally, creating partnerships within the same industry network to strengthen relationships will help increase access to customer groups. The use of technology, online media, and social media can help enhance communication channels, providing a more systematic service experience, which in turn increases trust and confidence in the services provided.
