The owner is rude

Had breakfast at spur , service was awesome. Came back later to tell the cashier I'm still full of the breakfast , she told me the owner is calling me. I went there , he greeted , he asked me where I worked etc. next best thing he says very abrupt I can't use the toilets and he spends a lot of money fixing up the toiltets with people of the public using the toilets . He was so rude , why didn't we go to his office , he screams in the resturant where there is customers , I just walked out , as I walked out he screamed at his waiters . Worst management ever .
