Dunno if this is what you’re looking for, but I ran into one of my team’s mentors while finding a place to sit at a Bernie Sanders rally. Mostly unlikely because I thought he was a conservative. 
Two cool ones here:
1- A TSA agent that was checking our team at the Philly airport on the way to St. Louis in 2013. He was on a now retired FIRST team in Philly as a kid. He recognized our team logo and we talked for as long as you possibly can talk while going through security.
2- Ran into a MOE mentor while touring the Ancient Roman Baths in Bath, England in the summer of 2008.
I’ve found a surprising number at music events. At the Marrowstone Music Festival, a big symphony gathering at Western Washington University, I met three. We’re everywhere.
I think every time I have worn a robotics t-shirt while coaching at a cross country meet I have had at least one person from another team come over to say hi. Our FRC team has a lot of XC and track athletes because I coach all three sports. Not sure why there seem to be so many crossover athletes on other teams but there do seem to be. One year at Crossroads some of my kids almost pulled off having an informal race. They found four other FRC teams with enough runners to make a full cross country team.
I often where an FRC polo shirt when I fly, because more often than not I make a connection with someone along the way who is involved in FRC. On one flight the woman sitting next to me and I talked for about two hours about sensor integration and how to find good human players.
It’s in Minnesota. Lol that was me
At my old job at a grocery store near me, someone came through my lane wearing a 1501 t-shirt that she apparently got from a family member? (Huntington is relatively close to Fort Wayne, but it was still a tad surprising)
While it wasn’t unusual for me to meet FRC people at MIT (or see people wearing team shirts), it was very odd when I saw a kid wearing a sweatshirt from my team in Florida. Mainly because we haven’t had another student at from my school at MIT in decades, it was ~10-11pm coming off the subway station (so not a tour or anything like that) and I didn’t recognize the person at all.
Turns out he was a 79 alum. 79 and 744 have always had a good relationship and I guess he traded with someone.
The grocery store.
There was a random kid I didn’t recognise who had an FRC game pin on their school blazer. It might seem “normal” to some, but when there were no teams on the continent 7 years earlier, it’s pretty cool!
The opera.
Several years ago, the parents of the Team Captain of one of the local team sat in the row in front of us. I think they were also mentors to that team. Last night, the coach for an FLL team was sitting next to us. I had just met her at the FLL Kickoff the previous Saturday.
A cruise ship.
Last December, I met the head mentors (husband and wife) of a Dallas area FRC team on the first day, before we had even left the dock. We met up a few times more over the next few days. Their team were finalists at the Lone Star Regional this year.

I remember the rest stop!! On our way down to NC this year right?
That’s right! It was on the way to NC! I don’t remember what state the stop was in but what were the odds of us meeting at the same rest stop for lunch at the same time on such a long trip? Thanks for remembering that. Good times.
Edit:
Pardon my misspell from my previous post. I usually catch such an obvious English mistake before posting.
A few years ago my high school jazz band went to the jazz festival hosted by Rolling Meadows High School. Not knowing the school had an FRC team, walking towards our homeroom for the day I passed by a blue banner hanging up. Thinking, “Oh! They have a team!”, I saw another dozen banners before realizing exactly which team it was…
Unfortunately, I didn’t get to meet anyone from 111 that day.
I was wearing a Robostangs shirt to driver’s ed and it got recognized.
And when I was flying to a wedding I was wearing my team shirt, a TSA agent knew us!
I suppose it’s not exactly unlikely, but I still find it funny:
I’ve set aside Wednesdays outside of build season this year to be a night off from robotics, when my husband (also a mentor) and I can go play games at one of our local game shops. Of course, I got into a conversation about robots with my opponent, and somebody at the next table over asked me “I hear you talking about robots and CNC… do you do FIRST?”
Turns out that our day off from robotics is actually our day of hanging out with another local lead mentor.
I met a FIRST volunteer at an ice cream competition in the historic center of my town. She was wearing the big plastic merch earrings.
I was in the vendor area at DefCon this summer (24K people at a hacker conference) and talked with someone wearing a Stronghold shirt. His son, a team member, was there.
I got a new one.
This week, I was at Oracle’s OpenWorld conference (their major developers conference with 60,000+ attendees) demoing our robot and presenting the robotics team. While there, I happened to meet the dad of a student on Team 766, which was a pretty chance occurrence considering the amount of people there!
