My issue is the boneheads who watch 50 people in front of them go through and then:
Look puzzled when asked if they have a laptop
get out their laptops out of their wee tumi bag
remove their coats
find the liter of evian water in their bag from the previous flight
try to drink all the water but give up after 10 seconds
have an argument
go through
come back
remove their belt that sets off the detectors most times they travel
blah blah blah....
You forgot to be forced at some airports to remove shoes, put on plastic "foot gloves" and put the stinkers through the machines.
Although I am generally against the new generation of scanners which show people "naked" - last week in DME they worked damn fast. Go into the cabin, stand on pre-marked spots and raise your hands. Then the machine drives once around you (whoever had an x-ray done at a modern denstis knows what I mean) - and that's it.
I was allowed to leave my shoes and belt on, had a lighter in my pocket and still was allowed to leave. And it was NOT that they were not watching their screens, others had to unpack their pockets.
