8.being a regular customer:
I do not refer to my “regulars” as customers. Doing a one time job for someone (like someone selling their home) I would refer to as a customer. I am a professional and offer professional services.
I’m sure most of you see this as semantics, but when you use the word “client” in your advertising and in person, it has a psychological effect. Think psychology of sales.
I also refer to my clients on a first name basis. I never refer to them as “Mrs. Jones or Mr. Jones” . I am an equal, not an underling. Referring to them on a first name basis has that same psychological effect.
That’s my two cents. Take it for what it’s worth.
