Final answer:
The concerns that compel companies to take action immediately are quality of merchandise, quality of service, and an employee's lack of courtesy.
Step-by-step explanation:
The concerns that are mentioned in the question and compel companies to take action immediately are quality of merchandise, quality of service, and an employee's lack of courtesy.
These concerns are important for businesses because they directly affect customer satisfaction and ultimately the company's reputation and profitability.
For example, if a company consistently sells low-quality merchandise, customers may become dissatisfied and switch to a competitor.
Similarly, if a company provides poor customer service or employees lack courtesy, customers may have a negative experience and choose to take their business elsewhere.
Therefore, it is crucial for companies to address these concerns promptly and ensure that they are consistently delivering high-quality merchandise and service while promoting a culture of courtesy among their employees.
