It doesn't matter how you change safety briefings a large percentage of passengers are actually completely thick. You can see this when they turn up at security with 8 gallons of unidentified liquids, get confused and can't seem to follow signs to the appropriate gate, have no concept of time and wonder why their luggage is offloaded, and turn up for a Ryanair or Easyjet and get lost trying to find their seat number. Not to mention the woman in 1A into STN tonight that couldn't seem to understand that her bags had to go overhead. You guys find passengers frustrating you should try sitting with them!
