Oh yeah. I was waiting for the China Embassy visa line to open in Hong Kong. When the doors finally opened, 20 mins late, everyone made a mad dash for the 20 feet to the counters. One woman attempted to hurdle jump the rope line but caught her foot. SMACK she went down on her face, pulling down the entire rope line. Meanwhile the rest of the crowd, myself included I'm embarrased to say, trampled her.
Everybody pretended nothing happened. One of the workers quietly put the rope line back up, as if this was an every day occurance.
