I was approached by two women and now im scared.

So, as i was Walking trough Yoyogi Park, i randomly got approached by two women (around 40y an 70y).
They first asked where i was from and why im in Japan, the normal stuff you sometimes get asked politely. But them they handed me a Flyer for a Vegan Restaurant in Tokyo and asked me to sit down and wait. I got confused and at this point the alarm bells started ringing, so i startet to use a Translation App, because i couldnt understand what they were saying.
So apparently they wanted me to sit for a fews minutes and then i would feel better?
At this point it felt to sketchy and i quickly excused myself and left. They gave me their Instagram tho… It looks like they are like Eco Friendly Vegans or Something.

Im kinda scared now, had anyone have similar experiences or knows what this was about?
