auxiliary verb くれた being used in context of "having questions"


This question is closely related to a similar question I asked not long ago:

[送ってくれた : Why is both "sending" and "giving" being used together
here?](https://japanese.stackexchange.com/questions/57141/%E9%80%81%E3%81%A3%E3%81%A6%E3%81%8F%E3%82%8C%E3%81%9F-why-
is-both-sending-and-giving-being-used-together-
here?noredirect=1#comment98856_57141)

I now understand くれた being useful as an auxiliary verb meaning "did for
his/her/my (benefit)"

In this case I wanted to express a story to my Japanese friend about how when
I visited my girlfriend's father for the first time, he had a lot of questions
to interrogate me with.

My friend told me to say this: ​父さんはたくさん質問してくれました.

I did some more research, but I don't undertand how くれました is being used here.

It seems like it should mean this: "Her father had a lot of questions to give
me (for my benefit)"

I also came up with this variant on my own (is it correct?):
お父さんはたくさん質問して聞きました。 "Her father had a lot of questions to ask me."

Anyway, in the first case, the questions are interrogative, and thus not
necessarily wanted by myself, or for my benefit. Interrogative questions feel
more forced or imposed upon me, than "given" to me.

Am I misunderstanding the usage here? Is there a better way to express this?




This くれる is not really different from くれる in 送ってくれる you asked before. The
sentence just means Father asked a lot of question and _that fact was
beneficial (to you or your friend*)_. A lot of questions mean 父さん was
interested in you, and that fact itself is the beneficial thing here.

* I'm not entirely sure what was happening... maybe your friend and your girlfriend's father knew each other and was talking about you when you were not present?
