What the heck, make the triple threat happy....the new (two year old) GFI standards are intended to reduce nuisance tripping problems, so there's probable no harm in it.
As for the breaker issue, he ought to be happy if his push-button tester works.
Get the inspector to start visiting this forum before he gets contentious. It can get lonely when you're the only official "expert".
Another idea....have mayor "deputise" someone else -perhaps inspector from another town- to remove the issue of personal animosity from the inspection.
