Girlfriend's friends are touchy, normal?

*Story from a guy not from gag*

So it has happened quite a few times now, whenever we are meeting some of her friends, or if we meet any of her friends (guys), they hug. I mean its the way they greet so didn't really think much of it, but the hugs are quite touchy, some of them had their hands around her butt, and 1 even grabbed it but couldn't say anything.

To come to think of it now, im kinda thinking of breaking up with her, or should i tell her about it?
