This store is extremely rubbish. I went shopping, thinking that I was her son. After I bought the electronic cigarette, I was at the door of her store and hadn't left, but I found that it was not working properly, so I went back to the store and asked her what to do Her attitude is extremely unfriendly, as if I owe her money, get rid of it, I am going to consume and buy things that are broken, you are not responsible?
