Today our CEO sir scolded me because tea lady didnt brought tea for him on time

He was scolding telling me that I should do his work leaving all the work behind since he is CEO then I also cant tolerate so I also cried so much. I work like non stop in this office and I am responsible for so many works of many department works like admin, account, IT, store, procurement and even HR. I wouldnt feel bad if I would have habit of skipping the work but I am such a dedicated hardworking person and just because tea lady didnt bought tea for him on time, he cant scold me like that. Working under other is such a hell sometime. Later on he was telling me not to take things personally but I have already taken the things personally. I used to praise him as the perfect CEO and now he is in one of my hate list.
