What embarrassing moments have you had during your trip?

The most embarrassing thing is that we have no change when we take the bus. At that time, we had calculated the money for taking the bus. As a result, because the bus is 1.50 dollars, 50 cents more than usual, so we have no extra change. At that time, we didn't have a mobile phone to pay, and then we borrowed it from people around us. Everyone hasn't changed anything. We finally found some money and put it in, which was embarrassing.
