McGruber writes "Orlando Sentinel columnist Lauren Ritchie has written about how Transportation Security Administration (TSA) checkpoints handle her father Sam, an 87-year-old who has a propensity to question authority in a quiet way, and make his target feel stupid. Sam points to the signs that the TSA posts stating that those above the age of 75 don't have to take off their shoes for screening. Maybe the TSA thinks all old people wear floppy tennies, but Sam's favorite pair have metal. So every time Sam goes through the screening, an alarm goes off, and an officer makes him remove his shoes. And every time he feels compelled to test the TSA. Sometimes, Sam spots them a few points by warning them ahead of time that his shoes have metal.... it got to be a ritual for a while, ending with him throwing his hands up and remarking to the TSA person: 'Hey, something's not right here.'"
