Appalling attitude by front door lady

Upon walking up to the Standard Bank branch in Bedford Centre I noticed a line, feeling nervous about standing in the line whilst carrying more than 800k cash I walked to the front of the line and apologised to the front lady and the other customer for interrupting. Wanting to find out if it were okay for me to stand inside until it was my turn to be served, I proceeded to ask my question, mid-way with the most appalling attitude she told me she is helping the other customer and that she had a line, ignored my question and walked away leaving me confused on what to do. And now I ask if I were to be ****** standing in the queue would Standard Bank take the responsibility?
