Once it was very serious, because I went out late, I missed a bus and later changed my ticket. Who knows I need cash to exchange tickets? I rummaged through it, asked the passer-by, and ran to the nearby bank to withdraw money. The cashier had no money to withdraw money, so I had to take the number to withdraw money. On the way, I missed another bus. My mood at that time was like this. I regretted it and waited. Then I looked at the ticket page, the last bus. Fortunately, I finally got the cash and signed the last bus, but I wasted more time because of the delay.
