Rude staff member

Good day Today I went to an atm in wilrogate in Roodepoort . There was a lady infront of me who I thought is a customer but she a Standard Bank employee who was tidied the atm and was taking pictures. The lady was rude when asked her if she could have waited for us clients to use the atm and she can do her duties . She was very very rude . Can Standard Bank please look into this .
