Clarification: The woman wasn't a client, she works there. Also, she's the owner's mother (who apparently isn't a JW) and he asked that everyone just ignore her. Mike throws all the watchtowers she leaves in the break room into the trash.
She actually got quite volitile with Mike over a bible passage that she claimed wasn't true. She called the elders, loudly, and apparently got told the same thing Mike told her, because she got quiet and looked completely shamed.
I'll ask Mike about what passage it was.
