Also the flt was delayed as we waited almost an hour for people trying to connect which made me more upset since I was rebooked on that later flt because although my previous flt was there half hour before departure, we didn't have a gate to use which caused me to be 15 mins late for my original flt. Did they wait for me?! NO! I was rebooked. It's unfair that they stole an hour of life from every other passenger to accommodate a few. Back to the guy who puked, an hour after that he started shaking and grabbing his head and asking me why am I hurting his heart. Then incoherent blathering and then his last episode 20 minutes before we land in which he started hitting himself in the head saying he would die right now for his wife and how he's made mistakes. It was three separate incidents from this one passenger and not one flt attendant noticed? Yeah it was bad piled on worse stacked on top of never United ever again."
