Thank you for the encouragement!

Here’s approximately what I said:

“Hello, is there a manager available?” The Customer Service person took my name and asked what this was regarding. I said, “Well, this magazine was in your check lane right at my children’s eye level,” then I showed the magazine, “and I think that it is totally inappropriate, and I’m pretty upset about it.”

When the manager came, I introduced myself and my children (they make a good visual aid), and then said something similar to what I’d said before. “I was walking past your check lane and I saw this,” (here I showed him the magazine). “This is right at my children’s eye level, and as we go through the check lane, it’s practically impossible to keep them from seeing it. And it is completely inappropriate for children.” The man I talked to took it from there, but if the person you were talking to wasn’t showing much initiative, you could say that you’d be very grateful if the store would get covers or remove the magazine completely.
