Haunted attractions?

So in haunted attractions are actors allowed to touch you? Like grab you or anything like that? I was just wondering cause I went to one a few nights ago and before we went in someone who worked there gave us a little warning saying how to be careful going up and down the stairs, be careful were we stepped and that actors would follow us but they wouldn’t follow us or try to scare us going up and down the stairs. I’ve never been into one where they touched me until this specific place. I was not warned about being touched by the actors and no one else in my group was touched. It was only me that was touched. The actor came up and didn’t even try to be noticed he followed us and since I was in the back of the group he grabbed my sides and I just thought it was nothing until I felt him grab my sides again and I turned around and he smiled and laughed backing away.
