Small Voltage In Green Wire


Was over building a garden shed for a friend and we had to use his neighbor's outlet but couldn't find the switch for it so I had my multi meter out to see when they found the right switch and just for hahas, I checked the hot vs ground (third prong) and had about 90 volts (after they found the switch).
But it was 120 black to white ( couldn't see the wires, just the outlet) and 14 volts between green and white.

We just used it and went away when we were done. It worked fine.

Is this something he ought to tell his neighbor to have checked out?

What could cause that small voltage reading in the ground?

loose or disconnected neutral that is either part of a multi wire branch circuit, a feeder or the service.
