Interpreting the use of "お日柄もよく" on this scene


I'm talking about this scene:
[https://youtu.be/e7E2AQQ6lGQ?list=PLxWrrb3wgaZ0RZAgITSqwGrWBsuur1lxz&t=670](https://youtu.be/e7E2AQQ6lGQ?list=PLxWrrb3wgaZ0RZAgITSqwGrWBsuur1lxz&t=670)

Context: A yakuza sees some delinquents beating up a guy. The street happens
to be his crew's territory so he teaches them a lesson. The guy who was being
beat up then tries to thank him and an awkward moment happens where the yakuza
glares at the guy as if to say "I didn't do this to help you". The man then
awkwardly says: いや,えっとこのたびはどうも...お日柄もよく

From what I gather, お日柄もよく is a phrase often used in weddings and other events
to refer to the day in question as an auspicious or lucky day. How does that
apply to this specific situation?




Simply, this man was very confused, and said something that doesn't make sense
just to buy time. After all, almost no one knows how to speak properly in
front of a yakuza who saved them. Weather is one of the common topics when you
don't know what to talk about, so perhaps he wanted to say something like
いい天気ですね. But he somehow felt this was not polite enough in front of a yakuza,
so he ended up saying the formal wedding cliché, お日柄も良く. (Strictly speaking,
お日柄もよく doesn't mean 天気がいい, but they are s somehow similar...)
