Thank-you for your prompt and courteous reply. I’m aware of the Village People’s ‘YMCA’. Just now picked up on the fact that this is in the TSA body scanner at the airport.
US Air Force Basic Training, the Military Training Instructors (MTIs) all had taps on their boots and shoes. I served 20 years, retired as a Master Sergeant, and Basic Training was 41 years ago. The sound of steel taps on any hard surface floor STILL makes my various sphincters reflexively slam shut.
Okay – this one was funny.
