Standard Bank Tellers Refuse to Assist Clients in-Branch

Yesterday I had to deposit a fairly substantial sum of cash at Standard Bank Newmarket Mall, Alberton. As I entered the meeter and greeter told me nope sorry, I must do my business outside at the ATM's. Maybe it being the day after a public holiday but that queue, for the ATM's snaked through the parking lot and around to another entrance of the mall. Inside the branch was relatively quiet. So, there I was, standing for what felt like an hour, probably closer to half an hour with my substantial sum of cash breathing exhaust fumes from the parking lot, blazing sun beating down on us all. Now, what would have happened if I had been ****** of the cash I wanted to deposit? There was not even a security guard to look after the well being of the Standard Bank customers wilting in the heat; they were hanging in air-conditioned luxury and quiet inside the branch while we, the customers were left exposed to the elements and vulnerable to attack from a bad actor in the hundreds of people swirling around us, trying to get through the blockage of the queue, trying to get to their vehicles etc.. Would Standard Bank have refunded in the event of a ******* after refusing me service in branch? Considering the set-up; bank employees sitting inside, in cool calm luxury, us customers outside in the queue shuffling through the parking lot and mall entrances, vulnerable to attack every one of us - the answer is most likely a resounding No. Since when do tellers refuse to service their clients in branch? Did I miss something? More importantly what is their legal liability in this instance of blatant dereliction of duty on the part of Standard Bank?
