Final answer:
A restaurant owner is most likely to enhance employee training to reduce problems associated with service intangibility, as it directly improves the delivery of service, thereby building customer trust and satisfaction.
Step-by-step explanation:
In order to reduce problems associated with service intangibility, a restaurant owner is most likely to enhance employee training. Service intangibility refers to the fact that services cannot be seen, tasted, felt, heard, or smelled before they are purchased, which can make them harder to evaluate beforehand. By enhancing employee training, the owner can ensure that the service delivered is of a high standard, which helps in building customer trust and satisfaction.
Offering online reservations could also improve customer service and organization within the restaurant, but it does not directly address service intangibility. Improving interior decor could make the environment more appealing, but again, it doesn't address intangibility in the way that training employees does. Increasing menu prices would not have a direct impact on service intangibility and could potentially deter customers if not justified by an improvement in service or food quality.
