It can be hard enough answering customer’s questions when they’re standing in front of you, but what if they’re online? Words are misinterpreted and tempers flare much more easily. What you write as a humorous comment could be seen as offhand and rude.
Potential customers will always ask questions. They may be about your service, your product or when you can deliver. If you offer a service that needs a face to face meeting your customer must decide whether they want to spend any time with you.
