Haha what a great story, Mate!
It can be a part of a movie.
Chinese guys have the most dirtiest things in mind. Always and everytime. If you talk with them, every third word is a lude one. Not same as we say fuck. I mean really dirty. And they like to this everywhere. In public, there not shy.
You sure they are chinese? Not japanese?
In japan there is a group celebrate nude sumo. Thats a more serious thing. Nothing behind.
But what you like to do now. Just want say some sorry?
You can give them a free ticket to access your websites and tell them " hey guys thats my biz"
maybe you get priceless connections
