Customer service at an exceptional new low - Game Clearwater Mall

The company I worked for sent me to Game Clearwater Mall on 16 November and we were there at about 15:15 to get a quotation for various items we need to purchase. A lovely lady name Vanessa helped us and I was really impressed with her service; if it wasn't for Themba, this review would have gotten 5 stars. She wanted to check on the computer if they have enough stock for a certain item we required but she needed someone to enter a code into the system so that she can check. Themba walked past and she asked him to quickly enter the code, but he turned around and made a gesture that he is going to eat, mumbled something and walked away. I almost followed him out of shock to ask him to take 5 seconds of his eating time to help us as a customer and enter the code. Instead, I stood there in shock. I told my colleague maybe we should go to another store, but if it wasn't for Vanessa we probably would have left. Appalled by Themba's behaviour. It's disgusting to think this is the level customer service is at, even if it is only one person!
