I’m about the write racially sensitive stuff, if you’re offended, don’t read on!
Twelve years ago, I had a knee replacement. A while later, I bought a ticket and went through San Jose, CA metal checkpoint. I thought I had nothing to worry about because the knee replaement manufacturer gave me a card to show to the scanners.
HOWEVER, the card was written in English and the scanners didn’t read or speak much English. I set off the alarms, tried to show my card to someone, including a supervisor who also didn’t speak English.
Fortunately those in line were patient. And one called over a San Jose Police Officer who read my card and waved me on through.
Moral of the Story: Well, there’s isn’t one. Everything is FUBAR!
