Frankly, most CIA people sit at desks and do research and analysis. I do know a few who worked for the State Dept, CIA, and top secret SEAL missions. In great contrast, even when I know these people well, I hear NOTHING beyond their employment. NO DETAILS, even little insigificant ones. I've also heard people brag at parties.
The consequences of repeating anything are very serious: prison (hard time), jeoopardizing a mission, losing your security clearance (w/o it, you have no job), end of your career, no pension. Bad reference for a possible new job. I am very impressed that I am told nothing. Not even an inkling.
When people admit they are foreign service, etc. but don't reveal rank, name, or serial #, I believe them. When they brag about their work and reveal operational details, they are actors, IMO. Please, the whole thing of saying you work in Langley, rather than the CIA, or go you to school in Boston, (Harvard) are old tactics. You know enough of the culture to fool people with a little bit of knowledge.
I am getting old b/c I would call the CIA and Homeland Security and report the incident just in case he is CIA. If he is CIA, it is unpardonable and a major crime. Loose lips sink ships. Maybe he was the exception, though. I worked next door to the WTC, saw it fall from my apt. It transformed me. Heck, I always used to speak with the NYPD asking for any details they could give me. After 9/11, I took a taxi to church. The whole area was completely surrounded by National Guard, FEMA, NYPD with automatic guns. The bomb squad trucks were in the intersection. Big German shepherds were sniffing all over the place. The church is next to the hotel where foreign diplomats stay. I meekly asked if it were safe to go to church. Rather than chatting, I Had no questions. They told me it was perfectly fine. Right. I don't want to know scary stuff.
My PT appts were in a major corporate bldg. It took four hours to get in the bldg. I knew it was a high value target. Rather than call and ask the FBI if they were monitoring it, I just went. Later, I found the whole place was rigged with sensitive biochemical detectors.
