customer service at its best

I was returning an item for my sister. It so happened that the plastic I used put some dirt on the item. Thandi, who was supposed to override the item then told me I couldnt return a dirty item. We then argued back and forth but to my surprise she remained calm and polite the entire time. I just want to commend her on her people skills, she can teach a lot of people in retail a thing or 2. I must be completely honest, Thandi is really good with people, she was able to take a situation that could've easily went out of hand and she instead made sure we both laughed before I left the store... Thank you Thandi for showing great customer service
