The coffin on display thing is quite common for Catholics. It's usually at the home of the deceased, but as he lived alone, that wouldn't be practical. In Ireland, you might have the coffin on display at the Funeral home, and the family / friends would be expected to go and sit with the deceased for a while before the funeral mass. Or at least, take a walk past. It's a practice that gives me the heebie-jeebies to be honest, as the Irish (either side of the border) tend not to embalm the deceased. Requesting that you're on display in a public place is a bit beyond the norm tho.
