This reminds me of when I accidentally "crashed" a yakuza meeting. I was still (compared to now) new in Japan, and was outside a train station in Tokyo waiting for my friend. This particular station has a quite nice and expansive courtyard; however, there is limited seating. So I see what I assume are two different groups of people seated along a span of three benches, with one open bench in the middle. I decide to take said bench. Once I sat down, I realized it wasn't two groups but one. I also noticed that everyone stopped talking. Suddenly one woman in the group laughed, and everyone else followed suit. A larger gentleman in the group then gets up from his seat, and not saying a word, comes and sits right next to me -- so close that our shoulders are touching. I was a bit surprised but didn't think much of it, gave him a "sumimasen (excuse me)" and scooted over a bit further. Once again the group all laughed. I then gave the group a quick look and noticed all the trappings of the yakuza: metal briefcases, the hairstyles, the suits, frequent use of "aniki (yakuza term for big brother)," and yet it still didn't click. The big guy next to me was laughing the whole time. Finally, my friend showed up and I left. I tell her about the big guy that sat next to me, and how weird it seemed. As I'm relaying the story to her, everything fell into place and I realized -- "Holy f###, those guys were yakuza!" In obvious hindsight, I realize the big guy was politely telling me that the seat was not available. My friend still laughs about the story to this day.
