There was a brother in one of the local congregations who did beautiful woodworking and made beautiful cabinets, hutches, etc. An elder and his wife in his congregation thought he should make some things for them for free.
My husband (never a JW) and I made the mistake once of renting a house to a JW. Once she was moved in, there were all kinds of things she decided the house needed and that we needed to spend money on including a bathroom remodel. At the same time, her JW friends tore up the yard driving in it and tore up a door. We finally had to invite her to find other lodging.
My own brother has been expected to work on cars for congregation members for free. He works shiftwork and would be expected to spend time he should be sleeping doing for other people. His wife was a part of that. She was always volunteering his labor.
I think there is very much an expectation among JW's that others in the congregation can do for them.
