Sam's Club review: Management

I was at the Tuscaloosa Alabama store today around 2:15pm today and I had my emotional support animal with me.I was out of his sight for 20 seconds at the most,the a tall black gentleman walks up and said a service dog doesn't bark he has to go.I have no problem with that but as I went to show my ESA card he turned and walked off,it was three others with him two white gentlemen a black gentleman and a black woman that looked as him like at least he could have listened and let me explain that I have cancer and that is the only reason I had him, I go to Walmart supercenter Northport,Alabama,and have no problems. I just wanted to let you know how some people you employ are.
