Speaking of proper lines, when my flight was boarding yesterday, I was first in line. A lone gunman was standing to the right while the line was queued to the left. I told everyone that could hear me that he was a local and either had no concept of courtesy or no concept of what the hell we were all doing in line but that this was a common practice. And not to dare let him get ahead of them. Well about 8 made it before he wedged in. When in Rome . . . When I don't see tourists, I just join right in with the line crashing. It's not too hard when you are 1.9m and 95.5 kg.
