A few months ago I was going through security and put my metal objects (cigarettes, coins, keys, etc.) in the plastic container and tried to hand it to the little foreign lady at the walk through metal detector.
It took her at least 4 or 5 time to tell me that the container had to go through the conveyor detector before I understood her instructions. I'm a little hard of hearing, but if I had said "what" a few more times I'd have felt like a light bulb:)
Lately they have been arresting,imprisoning, and/or deporting all the airport security personnel around DC who were either illegal aliens or felons; if they will also deport or imprison the ones who can't speak or comprehend Englis that may be useful. (Especially if they don't get to vote for the more idiotic and moronic poltical candidates--if any are more idiotic or moronic than any others.
