【正确答案】 Dear Anne,
I am sorry to hear about your unpleasant experience with the taxi driver. I am sure most taxi drivers in our city are decent, kind and willing to help foreigners. But, unfortunately, there are always a few people who prize money too much. I suggest that you should ask about the price before taking a taxi next time, and make sure a taximeter is in place before getting into the car. Moreover, it's also important to ask for the invoice before payment so that you can contact the taxi company or relevant government agencies in time if you sense that something is wrong.
Wish you a pleasant stay!
Sincerely yours,
Li Ming
