Shan Xi Magic Kitchen overcharged tip

I have been a long-time customer of Shan Xi Magic Kitchen, a Chinese restaurant in San Diego that serves Shanxi cuisine.

The last time we went there, the waiter overcharged me for the tip. Although I paid $101.00 in total, a few days later, I noticed that I was charged $105.23 on my credit card. It was easy to detect the fraud because I always tip so that the total amount becomes a natural number. Furthermore, I keep track of all my expenses using personal finance software.

This is actually the second time that this restaurant overcharged me. The first time, I thought it was just a mistake, and I did not take any action. If it happens the second time within a relatively short time window, it must be on purpose.

I have disputed with my credit card company, and they will credit me $4.23. I have written a one-star review on Yelp. We will never go back to this restaurant.
