I said, "That is not possible if everything metallic is properly bonded.".

Glenn replied, "I have been on many trouble calls where someone is getting shocked from the kitchen sink even to the shower."

Could you please suggest for me a path that the current may have followed and why proper bonding did not prevent this (even when the neutral was disconnected); or more to the point, how bonding created a shock hazard that wouldn't have existed had the water pipes and gas lines not been bonded?
