I worked next door to funeral home for 4 years.
Funeral homes are always close to or in residential/commerical areas by design. The older funeral homes were exactly converted homes with undertaker living upstairs. A third cousin of family was an undertaker they lived upstairs.
Funny thing my old roommate from college worked out of funeral home back in 1980's (ambulance service) and when I went to visit her, I slept on couch in viewing area of funeral home. It took few minutes to get used to sleeping in there. LOL Thank god there were no bodies in there.
