Deposit Fail due to lazy staff

I went to the Nedbank in Braamfontien to make a deposit of over R5000.00. I was told to make the deposit outside as they no longer make any deposits below R250000.00 inside the branch. The queues outside were very long and everyone was told to go outside. As I walked in I was greeted by 3 ladies sitting and talking while eating crisps and the bank was empty inside with no client being assisted by the tellers at the moment. I had to join the queue and stand for over 20minutes because the staff at Nedbank have become lazy to assist people. There is no customer care. If Nedbank has enforced new processes for no withdrawals below R25K does this not get waived when the queues are long outside and the banks are empty inside? Is this not taken into consideration that if they have the time and ability to assist in that moment they will instead of pushing us all to go outside and leaving us to deal with the poor security guard who was trying to control the queues.
