My issue at Lowes Build and Grow Clinic

We go to Lowes Build and Grow almost every time they have it. We have been going for well over a year now and the kids love it. We have alot of wood projects around the house!!! Needless to say I was informed yesterday that I cannot take pictures of my children while they make their projects. We supposedly have never been allowed to take pictures but I am just now being told???? I don't understand why they will not allow this but they won't so this is one activity that may be dropped.
