@BillRM,
You can't just assume two things, you've not assumed how the Romans would have reacted for starters. You've taken those two things in isolation to everything else.
There's loads you don't know, how regular these occurrences were, how people were expected to behave in the temple, what constitutes societal norms. How were the moneylenders themselves viewed? Were they admired, hated or somewhere in the middle?
There's a **** ton you don't know, so you can't possibly extrapolate how one would behave in such circumstances because it's completely alien to you.
