They really can. And you should know your rights. The death industry is slimy AF, about on par with timeshares. My late mother-in-law was Lisa Carlson, a pioneer of funeral rights and ethics. If you are going to be dealing with someone's death or planning to die (and you should be prepared), it's important stuff. You don't want to get suckered when you are so emotionally vulnerable, on which the death industry preys. There are a lot of options which the death industry tries very hard to keep hidden from you and lobbies to remove.
