This is my fanon as well.



More specifically:

1.) Granny Smith's rocker is held together with glue made from the hooves of her late husband, to remember him by.

2.) Gustave La France's restaurant charges very high prices, partially due to the paperwork even such a nice place as Equestria requires, and partially so the bereaved of the main courses will have an some more bits until the life insurance comes in. Naturally supply varies on a daily basis, and that from the DR is even more expensive than that from the retirement home. Gustave enjoys a spirited exchange of letters with Celestia and Luna over the completely hypothetical case of who would have dibs on carrying out the sentence on anyone who "hurried matters along" to his table.
