Explicit Rap musics being played in store

I was in the Checkers Hyper in Heldeberg Centre on Sunday 16 February 2020 and in their Tech X dept, the salesperson was playing music through the speakers on display. I don't have an issue with that, but what I do have an issue with is the type of music he was playing: explicit rap music - all the swear words you can imagine. The music was being played extremely loud, louder than the actual store music. Checkers is a family store and this is not the type of music I want my small children to listen to.
