**1. Currency Used in the Country:**<br />- The currency used in my country is the Vietnamese Dong (VND).<br /><br />**2. Famous People, Places, or Things on Bank Notes:**<br />- On Vietnamese bank notes, there are images of famous historical figures and landmarks such as Ho Chi Minh, the Declaration of Independence, and the Hanoi Citadel. These representations are chosen to reflect the country's rich history and cultural heritage.<br /><br />**3. Exchange Rate of Currency to US Dollar:**<br />- As of the latest update, the exchange rate of the Vietnamese Dong to the US Dollar fluctuates regularly. For accurate and up-to-date information, one should check a reliable financial news source or currency converter.<br /><br />**4. Payment Method: Credit Card or Cash?**<br />- It is generally better to pay with a credit card rather than cash because credit cards offer more security and convenience, especially for larger transactions. Additionally, many businesses accept credit cards, which can be useful when cash is not readily available.<br /><br />**5. Complaining About the Bill in a Café or Restaurant:**<br />- Yes, I have complained about the bill in a café or restaurant. This usually happens when the service is slow or the food quality does not match the price. Complaining helps to bring attention to issues that need improvement and can lead to better customer service experiences in the future.<br /><br />**6. Returning Something Without a Receipt:**<br />- I have taken something back to a shop without a receipt. In such cases, the store staff often checks the item for any signs of damage or use. If the product is still in good condition, they may offer a replacement or refund, although this can sometimes depend on the store's policies.
