During my recent trip to Qingdao, I visited Hēi Lǐ yè shì, a beer festival that I had heard about. As I was enjoying the food and drinks, I decided to take a break and use the restroom. Upon returning, I was shocked to find that my food and drink had been taken away. I was furious and asked the waitress why this had happened. She replied that I had not informed her that I was going to the restroom, to which I retorted that I did not need to tell her. One of the staff members then emerged and punched me, and the boss later came and tried to escape responsibility, saying no one had seen the incident occur. He even dared me to report the incident to the police. I decided not to escalate the situation and let it go.
