Double Standard

I was very disappointed today when I went to First National Bank in Witbank down town to ask for my business account bank statement, I was helped by a consultant(Nomthandazo) who took more than 20 minutes to give the statement after that she started asking me questions and finger prints while I already verified through my ID and also through the questions she asked after giving her my ID. I have been using FNB for more than 15 years, this has never happen where I am treated like a **** even when I have identified myself. If they doubted my ID document why did they agree to open an account for myself. In my branch it once I produce my ID it takes less than 5 minutes to get the statement.
