Appeared, and such a bad situation was alleviated. The author of the self-service ticket vending machine himself has such an example. One time we visited the scenic spot, we were afraid of queuing to buy tickets at the gate, so we booked the tickets online, because we didn't want to go to the scenic spot to line up to buy tickets under the sun. But the last facts disappointed the author and friends. When we went to the scenic spot, whether it was the people who bought tickets on the spot or the people who ordered and collected tickets online, there was already a long queue.

Borrowing an advertisement to say, 'Mom, no longer have to worry about my ticket station for a long time! '. The self-service ticket vending machine is magical in the eyes of the author. It takes less than 2 minutes to buy a ticket, and you can buy it when you arrive, so you don’t have to worry about buying a ticket.
