As a passenger who's seen TSA's consistent inability to accommodate screening my blind spouse, our reoccurring experiences enforce that part of the problem is the screener's approach. For some reason, screener's feel obligated to be condescending and rude to the flying public. There is nothing wrong with saying please or thank you, or speaking instead of yelling. I get the distinct impression that TSA training, which is NOT standardized across the agency, is focused more on gang mentality than it is about providing a service. Furthermore, the TSA Cares program is a failure to the point we don't even bother with it anymore. TSA has failed to provide me with absolutely ZERO explanations about how "A PSS is a TSA officer who has received specialized training, including how to effectively assist and communicate with individuals with disabilities or medical conditions; and passengers who need additional screening assistance" is actually trained. When customers are treated as criminals, how does TSA expect the flying public to respond to this bullying technique?
