Anyone who has found themselves in the position of having to hold their bladder in check for a long time will understand this.
Kima Hamilton was on a Delta flight bound of Milwaukee and had to go. He was told he could not use the restroom by flight attendants. So he waited. Finally, after a good 30 minutes, he couldn't hold it anymore and ran to the bathroom.
The plane was on the tarmac and when Hamilton got back to his seat, he was told he would not be staying on the flight. Attorney Krista Rosolino was on the flight and had her husband shoot video of the conversation.
Delta released a statement regarding the incident. "Our flight crews are extensively trained to ensure the safety and security of all customers. It is imperative that passengers comply with crew instructions during all phases of flight, especially at critical points of takeoff and landing.
