Think I'm stupid?

I recently registered a business and need a bank account. Seeing that I bank with Nedbank I decided that it may be easier opening up an account with my banking institution. A gentleman phoned me from the Greenacres branch telling me that he is skeptical to open a business account for me as he doesn't know if I will be able to maintain the account. This is despite me telling him that my partner and I are both permanently employed and are in the medical profession so we should have no reasons for concerns. We manage our own finances very well and I am very disappointed to learn that there could be a consultant who thinks that they can contact me and class me to a particular group of people. We all bank with the same moneyregardless of our, positions, profession nor skin color. Do you really think I won't be able to pay a R100 monthly account maintenance fee? Excuse me? I would have thought that getting an additional account should be a good thing for Nedbank but having to answer questions around it is very bad for the client. I'm not stupid.
