It's not about offending anyone. Lord knows there is way too much PC BS in the world. Just using common sense when there's likely kids around. If someone isn't too worried about their kids hearing swearing than that's their call...no biggie. But I would guess the majority of parents tend to want to keep their kids shielded a little from the grown up world as they are still kids. I know they hear stuff at school etc. that doesn't justify letting it rip at a place where kids are most likely there too.
