Office supplies use

Hasham asked 6 months ago

Salam
My employer provides filter 14-litre water bottles in office for employees. Now I drink that water all day. When going home, I fill my 1-litre water bottle from my office and drink that water in my home also.
Is it allowed?
Is it stealing?
I fill my bottle in front of everyone, but nobody ever said anything.

Please answer.

Thank you.
