"During our visit to Lemon Leaf Grill in Thailand to celebrate our daughter's high school graduation, our family was disappointed with the service we received. We were surprised to discover that the waitress had automatically added an additional 10% tip to our bill without our approval, resulting in a total tip of 30%. When we requested to remove the extra tip, we were informed it couldn't be done because we had already signed the receipt. This situation left us feeling frustrated and taken advantage of. We believe the restaurant management should remind their staff to prioritize honest practices, as they can significantly impact the restaurant's reputation and deter repeat customers. Additionally, it's advisable for customers to tip in cash when possible to avoid similar issues in the future. In the end, we felt disappointed and uncertain about whether the extra tip was properly accounted for and reported to the government."
