Reading previous comments I have this to say.
I went to a JW funeral a couple of years ago. It was friend of a friend and I did not know the lady apart from the fact that she was a JW. I went because the friend I was with was going and asked me to go along.
I was very surprised when I got to the Crematorium. There was a very good crowd there.
Apparently her family were not witnesses and I got to hear that the lady did not attend the church . However, the majority of people in attendance were witnesses. A leader of their church gave a talk telling of how long she had been a witness and how she loved her family and her God Jehovah. It appeared that she was a lady who was not very financially well off , there was no recriminations that she had not converted her family nor any mention that she was a generous donor financially.
After the service all were invited to the local pub for a pie and a drink. I did not go as I felt that not knowing the lady it would be an intrusion, so in answer to previous comments, it appears that they can be either buried or cremated. They do have a “funeral” tea, and that JWs do have a drink, that they do not force people to make monetary donations to their church and just because they do not go to all the services they are not thought of as outcasts. Unlike the regular organized churches. I know of a catholic lady who was only called on once a year by the local priest who delivered her weekly covenenant envelopes and when she was ill, no one bothered to call and see her. Also from my personal experience, the vicar only called to see us when mother decided to stop sending in her donation and he wanted to know why.
