I think most of us old are old enough to remember working in an environment with a constant sound of a ringing telephone. Answering that call was very important; it meant there was a customer on the line with a question, concern, or to make an order. In fact, it was so important; some companies hired answering services to take calls in the off-hours.
That’s changed, hasn’t it? The sound of a ringing phone has been replaced by email or perhaps your information on your web site. Your customers no longer need to call you to get the answers they were looking for. If they need to know your store hours, that’s easy. It’s listed on your website.
