THANK YOU! I'm pretty sure she has edited her posts to change the story as I am pretty certain she said the whole situation arose because of a blocked photo and being told she could not see it because it was inappropriate so instead of showing it, the cm did the pose for them and that was that.
Regardless, they all say photos are screened for innapropriateness when you go up to the counter to buy them so I don't see why you assumed there was anything innapropriate in the photo. If it appeared on the screen in the first place then there was nothiong wrong with it.
Although yes, I do feel it was innapropriate for the cm to say it in a way that it upset you and your daughter and I hope it didn't ruin your trip. However she only said it was 'innapropriate' (Whether it was or not) is totally fine. I'm sure she didn't shout and curse at you and what not. You should just ignore it and let your daughter do as she pleases, as long as only two fingers are extended next time..
