What is the main purpose of travel agency outreach?

The tourism industry is rice, the plan of the organization is cooking, and outreach is equivalent to the responsible contact person who buys food. Tour guides eat vegetables. If everything goes well during the guests' visit and outreach and planning work are done well, there will be no major problems. The boss of the travel agency is responsible for washing dishes and chopsticks. If there is a problem, then, sorry, the boss with the problem will come out to wipe his ass.
