Unexpectable Experience

I had a bad experience when I did shopping with my sister because of the shop assistance’s fault. She accused me for stealing a brown shirt.
That was a Sunday afternoon. My sister and I went to Jadi Baru Department Store. I went to the fashion store and that time I wore a brown shirt with a revenue stamp still adhered on it. I forgot to take it up when I bought it before. While I was choosing a T-shirt, a shop assistant came and asked me, “Have you paid the shirt you are wearing now?” I said, “Yes, why?” She asked me again, “When did you buy this shirt?” “Two week ago”, I answered. “But why does the revenue stamp still adhere on it?” said her. I said, “I’m sorry, I forget to take it up”. But the shop assistant didn’t believe me. She took me to the manager’s room. I was asked to take up my shirt by shop assistant to check it. After all things were clear, I said sorry to the manager and the shop assistant.
