This is why I think that TSA should police the carryon luggage. They see everything.
TSA ?! oh please don't even get me started on that!!
But I too have witnessed them stop a passenger and tell them they had to go back to the ticket counter. Both times the bags were so damn large they weren't even going to fit thru the x-ray machine.
Now just how stupid were those people to begin with? OOOPPS!! once again don't get me started!
