What does travel agency outreach mainly do?

The tourism industry is like a meal, the planners in the agency are the cooks, the external relations are equivalent to the responsible contacts for buying groceries, and the tour guides are the eaters. If everything goes well during the tour, If the external relations and planning and adjustment work are done well, there won't be any big problems. Also, the boss of the travel agency is responsible for washing the dishes. If there is a problem, then, I'm sorry, the boss will come out and wipe the butt if there is a problem.
