Really?

A few years back in high school i went to a careers expo. A prominent university had a small section there. Within that section were individual stalls for the faculties at the University e.g. arts, science, etc. I saw the business stall and decided to head over for some info (at the time I fancied starting my own business) and when I approached the woman (whose race shall not be revealed) she looked at me and said: "you know this is business right?" I was so offeneded that I was speechless. For awhile I was angry, and was going to get into business just out of spite. But I eventually realised I had no passion for business and did not want to work in an office, wearing suits all the time and climbing a corporate ladder. So I pursued something I gennuinely loved instead. I dont hate the lady or her race because of what she said, I just feel sorry that she has such prejudices.
