The handwritten thank-you shows that Cravens delivered on his promise.
"We build relationships with our customers, and if something is not right we are going to try to make it right," he said. "We are in retail, so we might not make everyone happy, but we try."
Cravens says he has instilled that philosophy in his employees.
Mandy Vermillion, 32, is a store manager for the GNC in Anderson.
"I love being able to help people and being able to describe things to them," she said. "I have been told I am an encyclopedia of nutrition information."
Vermillion said it is not uncommon to help customers struggling with weight loss, high cholesterol or other conditions to find the vitamins, supplements, minerals or herbs they need to accomplish their goals.
"These are people who are using natural ways to benefit them and their lifestyle," Vermillion said.
Vickie Riggins of Anderson describes herself as a frequent shopper at GNC.
"I really appreciate the fact they are an added benefit to the community," Riggins said. "The employees are trained, very friendly people and very helpful."
Cravens reaches out to the community by talking about nutrition and wellness at health facilities and a local hospital.
"I volunteer my time to help educate people on nutrition, life, health and motivation," Cravens said. "And I try to reinvest my money and time back into the community."
