@anniemaria The instructions clearly instruct you not to authorise them to collect the body.
If you're a rational person, then these shops are fine. I've done dozens of them. They're simple and easy. I'd do more, but the times conflict with my day job. Before I call, I always look up the address of the funeral home and find a nearby emergency room. I then write down my name for the call, the deceased's name, their DOB and age, their relation to me and cause of death (usually cancer).
I have my own server. so I can give whatever email address I desire.
I make everything up, including names and the deceased's name. I always make the person who died old so that the call isn't that memorable: An 88-year-old grandfather who dies of lung cancer isn't a shocking phone call to receive for the person who answers. I decide during the call if I want to cremate them or bury them.
Further, these calls are actually important: sometimes, the people who answer are great, but sometimes they're pretty terrible, and our fake calls help the companies that run them address that so that they can be less terrible to an actual bereaved family member.
All in all, they take me five minutes to prep and perhaps 15 minutes to complete, as the funeral directors tend to go on quite a bit. I'm fine with 20 minutes out of my life for this extremely easy shop.
I find others' squeamishness ridiculous. Everybody is going to die, and everybody you know is going to die. Some of them will be your loved ones, and some may die before you. Making believe that somebody is dead does not magically cause a real person to drop dead. If you're irrationally superstitious, then you can avoid doing these calls: you can also avoid stepping on cracks, breaking mirrors, black cats, etc, but I think that all of that is moronic. (I was going to say that if you're 'irrationally religious', but then I realised that I couldn't even think of any religions that teach 'jinxing' as dogma, so I downgraded it, as it were, to 'irrationally superstitious'.)
