Rude unprofessional bank worker

I went to the Brits mall branch to make a deposit only to find the atm not working and i asked 1 of the employees if we can deposit inside and she said yes. Now i go to the temperature scanner and took a ticket for deposit because she was helping a client and she told me to go out and snatched the ticket telling me to wait until she is done and by that time there is not even 1 client by the deposit counter. What a way to make banking simpler for clients, really disappointed
