A client recently needed some plumbing work done. Her usual plumber said he was "too busy" and wouldn't say when he'd be available.
Since the job was fairly urgent, she called another plumber, a young guy eager to grow his business. They exchanged a few texts, figured out what needed to be done, and set up a time that worked for her.
He got delayed on the way, but what he did next pretty much guaranteed him a lifelong customer. He called to let her know he'd be a bit late but would be there soon, and he arrived less than 10 minutes later.
The client wasn't bothered by the delay at all. In fact, she told the plumber she was impressed he took the time to call. He seemed a bit puzzled and said, "That's just common courtesy, isn't it?"
It is common courtesy, but it's often overlooked these days. Courtesy won this plumber a new client, while a lack of it cost the other plumber valuable business.
