"Overall, the food was quite good, but the service left much to be desired. When we paid with a credit card, we were instructed to “just sign, and you can leave the tip in cash.” Following the usual process, I filled out the receipt and left a tip at the entrance. However, the waiter returned and said, “I shouldn't say this, but we only receive tips if they are in cash. That’s why I asked you to leave a cash tip.” He then suggested that we leave the money on the table, and he would adjust the tip on the receipt. He refused to return it to us, and at that point, I felt like we were being taken advantage of, yet I felt pressured because he was hovering nearby. We ended up leaving some cash on the table and left the restaurant quickly. As I suspected, the credit card charge included the tip. I know this sounds quite suspicious, and although we intended to leave cash, this experience has ensured that we won’t be returning."
