What unpleasant experiences did you encounter during your trip?

In so many trips, there are many unhappy experiences, but these unhappy experiences often become the jokes of our happiness today.

Once I went to Chengdu Railway Station from Sichuan University with some friends. At that time, I brought my bike and temporarily put the pedal on the car, but I was the only one riding, and everyone else took the bus. But after riding for more than ten minutes, the right pedal fell off. It turns out that I put the pedal upside down, and the pedal nut and nut buckle slipped. Why can't I install it? What do we do? Ride with your left foot, step on the frame with your right foot, press it hard and stay in the air, then connect your left foot when the pedal automatically turns to the top, and so on. I didn't have time to look at the map on my mobile phone. I just rode all the way from south to north with a sense of direction, and occasionally stopped to ask for directions.

On another trip to Xi 'an, when I wanted to go home from Xi 'an, I had to go to the railway station by bus, but at the bus station, I talked too much with some friends. As a result, I didn't pay attention to the direction and sat backwards. After sitting for more than ten stops, I suddenly found something was wrong. As soon as I checked the map, the result was that I was getting farther and farther away from the train station, so I quickly sat back. When I arrived at the railway station, I looked at my watch. Yeah, not bad. There are still five minutes to leave the car. However, the high-speed trains are all on time and are not allowed to enter the station five minutes in advance. I said a lot of nice things, but I wouldn't let them in anyway. The train was delayed just because we talked too much.

But if the most unhappy experience is actually not these. On the train from Chengdu to Taiyuan, I used to sit in a hard seat, but my bike was in the corridor. I tilted my bike in the corridor. In order to take good care of my bike, I laid cardboard under it and slept and ate on it. I gave up my hard seat to a young man dressed as a gentleman. But after sitting on the train for more than 20 hours, this guy left without saying thank you when he got off the train. Although I didn't thank the train seat, I didn't even have this basic courtesy. I am sad. This is my most unhappy experience.
