This example sentence from (maybe) level 10, has 金 rather than お金. First example sentence for 最後.
This is the last time I give you money.
I was under the impression that when written, it should have the honorific to indicate it’s money and not gold. Is this not actually the case? Is it not like お茶 where it’d be bizarre/wrong to leave off the honorific? Or is this sentence supposed to be set in the past when some form of gold was used as money?
