In my retirement I work part time for an undertaker so I am in and out of cemeteries all the time. I have never come accross any rule like this and I think that person was out of order.

If its not going to make you dig a hole for yourself tell her that you don't like being put in a grave situation such as this and that she should get a life!!!!

Sorry for the jest, I couldn't help it but whatever you do, do not give up your photagraphy Christo.
