I’m thinking its also confusion about the backscatter X-ray machines that were used before the millimeter wave scanners replaced them in most places. I had heard some small airports still use the backscatter machines.
I still take the patdown instead of the millimeter wave scanners when I’m randomly selected for more scrutiny than the bog standard metal detector.



If taking an extra 15 minutes to go through security is causing you to almost miss your flight, then you’re already not arriving at the airport early enough. Shit happens. Gate changes occur. Overbooked flights are a thing. Long lines at bag check or security happen without any apparent notice or reason. Even something like unexpected traffic getting to the air port is common.
Welcome to the world the rest of us live in where the average citizen has to be the calm and collected one in the confrontation when dealing with law enforcement lest you earn their ire (or be shot because they’re nervous or angry).
