Bad Attitude At Spar Starwood

I went to Spar star wood , i spent 30 min waiting in the line to do a cash back withdrawal. When i finally got in front the lady told she doesn't have enough cash for me . (R1000) when i asked to ask another teller to help me , she said that is not her job , is there something wrong with my mouth that i cannot ask her my self . then she called the next customer .<br>
