Is seat kicking/hitting something you experience in your IMAX rocker seats?

Do any of you experience this in your IMAX rocker chairs? The adult behind you is moving their feet or body around and end up kicking or pushing on your seat. Seems to most often happen when they cross/uncross their legs or try to get the most leg room by shoving their feet up against the back of your chair. And they do it probably half a dozen times or more during a movie.

It's never kids. Maybe they can't reach even if they tried, but I've never had a kid be the one doing this.

If you're lucky enough to have recliners, I imagine this never happens to you and I am jealous.

And every time when I ask them to stop after the second incident of it happening, they get an attitude as if I'm inconveniencing them. Never an apology. I give everyone a pass on the first time.

It seems to happen almost every time someone sits behind me. :(
