This really happened:

I was calling funeral homes getting information about making pre-need
funeral arrangements for an elderly relative. The woman I talked with
at [name deleted] funeral home, just across the street from St.
[mother of Gods name deleted]s Catholic Church told me, …and that
cemetery requires a burial vault. Most of the cemeteries around here
now require a vault. The lowest price vault we have is $552. The most
popular one is $772 and it comes with a lifetime guarantee.
