How do Hong Kong tour guides promote their products?

In the tour group's itinerary, two shopping places were clearly stated: Tsim Dong Intercontinental Duty Free Shop and Xie Ruilin Jewelry. During the six-hour trip in Hong Kong, I will stay in these two places for two hours. Every shopping spot, the tour guide will do some publicity in advance during the driving process, and even take out some products for everyone to see.

Tour guides will not let tourists stay in the car for various reasons and ask everyone to go to the shopping place. Everyone will receive a tax-free discount card from the tour guide. In fact, one reason is that it is easy to calculate the head fee of the team led by the tour guide, and it is also convenient for the tour guide to get the commission from the tourists. Among the tour groups, some tourists suggested that the tour group reported in Guangzhou was free at the first stop, and the tour guide asked them to pay the departure fee in 30 yuan, which should be equivalent to the head fee paid by the store. They were very unhappy.

Please refer to the adoption. Thank you.
