Frankly those are the sort of passengers who probably should be forced to go to the end of the line. I was about 6 people behind someone in the expedited (first / business / aadvantage) line at American Boston Terminal B yesterday evening and first he had to be told to take his laptop out of this bag and then they held up the line for him while he looked for a baggie to put all of his things that should have been in a baggie in the baggie. I assume he was flying first / business class or otherwise got into the expedited line, but he was really slowing things down.
Or how about realizing that this whole liquid and baggie carnival is a farce does nothing to enhance our security and put an end to it. @:-)
