It didn't happened to be but to the couple in front of me. They did held up a queu for 10 minutes and when everyone behind me tooting their car horns, the driver (of the car in front of me) parked at the side and got me through.

As I passed, I gestured to the lady companion what's going on, she said "lost ticket, we need to pay QAR100"...I said "WTH????",.. and moved on.

Now I remember where I put my ticket where I could easily find it...QAR100???? Can you believe it???
