Im so sorry for you having that bad experience.
i would have asked Do JW have paid Clergy? When he of course answers No . Tell him he's getting paid to work so enough of the religious BS.
Back when i was a JW
When i have worked in similar industry i made a point of never instigating a religious conversation and never having the last word on it either.
No problemo.
Remember one old dude who had Watchtower n Awakes in a pile behind his front door ,it was a few metres tall! said they had been bringing him mags for the last 30 years and he had never even opened or read them. I just laughed and said you can turn them into pulp for his garden.
Glad you complained the nob head deserves it!
