I would either say you are most welcome.
You can say : any time!!
in Australia , People usually reply (No Worries) .
In Texas I heard people say "You bet!", very informal indeed.
In My country, we say:
You are welcome
Don't even think about it
No thank you
Nothing
thank you, too.
Never mind.
I often say:
- It's my luck.
- It's not a very big problem.
or only a smile![]()
