Chinese restaurant

I went to Dumpling Haus for dinner on Sunday. This is a Chinese restaurant located at the Hilldale Mall. Actually, I went there on July 4, but the store was closed. So, I was really looking forward to enjoy dumplings, which are one of my favorite Chinese food. However, I could not enjoy it because the store was closed again ! An old lady in the store said to me, "our closing hour is 6 pm and now is 6:05 pm. I'm sorry." I was very surprised and asked her to allow me to enter the store because it passed only 5 minutes. But, she didn't... I got a little angry about her stubbornness, but I still want to enjoy dumplings near soon. And, I remembered that one of good points about Japanese is to be punctual.
