What are your Flixbus (or any other coach brand) horror stories?

People, I want to know your stories: What are your worst coach experiences?

I'll go first: I was on a 36 hr Flixbus trip back to my hometown. At hour 16, I suddenly got nauseaus and quickly found out I got food poisoning from the oster festival I attended the day before. I started to violently throw up and couldn't even hold water down, so I quickly became super dehydrated. Toilet also didn't work, as usual. After a few hours I got so weak I couldn't move, I felt close to dying. At that point I just wanted to be finally out of that ungodly bus, laying next to the highway in the middle of nowhere, I wouldn't care. I had also only 1 % battery left, no distractions, it was just me and the food poisoning. Not only I was suffering, everyone else in the bus was too, because I was non-stop vomitting. For hours. Everyone was super helpful, but it must have been unbearable. In Bordeaux, two women next to me decided to get some fresh air, but the bus drivers that were under pressure to be on a tight schedule decided to just drive without them. We all yelled at them to stop, but they only spoke portuguese, so they aggressively yelled back and continued to drive. The women were running after the bus for almost a kilometer, when we got the bus to stop. The drivers were so stressed that they only waited for a few secs, then continued to drive, we started to yell, they yelled, they stopped, they started to drive, we yelled, and so on. Eventually, the women were able to catch up to the bus in all this stop-and-go nightmare, and we were able to continue our trip. At Pary Bercy-Seine, I had a layover and had to wait for an hour. I was so weak that I was unable to stand or sit without the support of a backrest, no bench or chair like that was close, so I decided to walk to rest my back on a ramp at the skatepark there. It looked welcoming and safe when I was there the last time, it was an afternoon, now, it was 5 am. The only people there were addicts, it felt like a dangerous situation but I was too weak to leave. They didn't come closer to me. They were scared of me. They held their distance because I looked like I was dying.

I closed my eyes for a little bit and after 20-30 mins I recovered well enough to use my phone and my remaining 1% that I carefully conserved. I searched for the earliest TGV, quickly bought a ticket, stepped into the train with my stinky, vomit-stained clothes and hair and was able to be home after 3-4 hrs instead of 10. I showered, rested and was comparably okay on the next day. Still took a few weeks to be at my 100% though.

TL;DR: What are your coach horror stories?
