I was impressed with last visit to Walmart. Keep in mind I have been into a Walmart twice in the last 14 years or so. Keep in mind this is just one element that makes up great customer service.
I have suffered & proven my entrepreneurial skills in a tough business & market. I have overcome impossible business challenges. I opened with $50K & have built a successful restaurant since 2003 the hard way. Nothing was handed to me. I worked hard & am willing to share my secrets. I definitely have some techniques that will help you.
