Final answer:
It is true that using positive body language is essential when interacting with customers, as it forms a key part of non-verbal communication that affects how one is perceived and contributes to effective communication.
Step-by-step explanation:
The statement that using positive body language is very important when approaching a customer, regardless of whether they are aggressive, passive, or assertive, is true. Body language is a crucial form of non-verbal communication that helps in creating a positive impression. Eye contact signifies engagement and an open body position conveys a friendly, attentive stance. It is important to be mindful of body language such as facial expressions and gestures, which can carry significant emotional information and impact how one is perceived. Whether in person or on camera, maintaining good posture is also important to convey confidence and professionalism. Effective communication involves being clear, concise, and respectful, avoiding too much or too little expression to ensure the message is understood without distraction.
