AITA for pouring my over creamed coffee cup into the full pot we all use so I can get the perfect coffee to creamer ratio?

I use cream with my coffee. Sometimes the coffees weak or I spill more than meant and it’s too creamed. So I pour the over creamed coffee into the main pot and pour again, it’s then perfect. The people I live with also use cream but they say it ruins the coffee and get all worked up. Usually Im a people pleaser but I think I’m in the right here. I don’t think it’s a problem at all and we all cream so From my view I’m helping everyone and reducing stir time while saving on multiple dirty coffee spoons. I would never do this if I was at someone else’s home.
