When our kids were about 8 and 10, we went into a gift shop in town and while we were looking at something, the kids wandered off and started laughing about some 18+ gifts on open display. The store owner got angry and said the kids were banned from the store. That was 25 years ago and I have never been back in there since. Nor will I. Small town or no, there are other alternatives if they're going to take that attitude.
