Identify the RBT from the following scenarios who is practicing professional conduct.

Jarret demonstrates professional conduct by greeting the bus driver each morning with a smile and a friendly "good morning" when assisting his client off the bus. This behavior reflects an attitude of respect and consideration for others, which is essential in a professional setting, particularly in behavioral therapy where building rapport and maintaining a positive environment can significantly impact client interactions.

Engaging positively with those involved in the client's care, such as the bus driver in this case, fosters a collaborative attitude and sets a tone for the day that can benefit the client’s experience. Professional conduct includes not only direct interactions with clients but also how one engages with other individuals in the process. By exhibiting such friendliness and courtesy, Jarret models appropriate social behavior, which can serve as an example for clients and contribute to a supportive and positive atmosphere surrounding the therapeutic process.
