Europe is now popular with an alternative "free" group tour, and I see publicity in every major European city. So, is there really a free lunch in the world? The first time I tried to participate in this "free" tour was in Paris, France, first based on the time and place indicated on the leaflet that the inn saw, and the staff grouped according to the language you need to explain. Because there is no Chinese explanation and no other Asian languages, visitors who come to this tour group can hardly see the oriental face. After the group was selected, the tour guide began to take us on a walking tour. The whole journey took about 2 hours and included the essence of almost all the attractions in the center of Paris. The tour guide did not take visitors to any shopping spots except to take you to visit the sights and explain. . After the trip, the tour guide will tell you that according to his performance during the tour guide, visitors can freely reward him. If he thinks that he has explained it very well, he will reward more. If you think that he usually does not "reward" a little, or you don't want to "reward" him at all, it doesn't matter. It is free and voluntary. In order not to make everyone "embarrassed", the tour guide said that if he wants to give him a reward, he will put the money in his hand and shake hands with him. He won't know how much he rewards. He will only see one in the end. In total, I found that most tourists are rewarding and have recognized his performance. Do you want to experience it?
