What should the tour guide do if the tour group discovers that a guest has not arrived before departure?

It seems that the situation you mentioned is that the guests are late during the tour. In this case, the first thing to do is whether the tour guide is responsible. He should inform everyone in advance of the meeting time and location, as well as the possible consequences if he is late. guest. If the guest is late under this premise, under normal circumstances, you should wait patiently for 5 minutes, and then call the guest to urge him. If he can come back in a short time, inform other guests that the guest will be arriving soon and wait patiently for him to come back. But when we get back in the car, we will reiterate the time issue in a tactful tone depending on the situation. If someone is late again and again, the tone will become harsh (used to scare guests) and the decision will be made based on the specific situation. If the passengers on the bus are very dissatisfied, or it affects the normal arrangement of the entire itinerary, then the measures for repeated latecomers are really to ask them to take a taxi to meet at the next attraction (provided that the attraction is not too far away) , but remember to ask all guests to sign as evidence. However, if the tour guide does not mention the concept of time in advance, then the tour guide must wait for the guest if the guest is late and apologize for his mistake. (As long as it does not affect the normal schedule) In short, it is very lively and cannot be too rigid. There are different ways to deal with it depending on the actual situation.
