Dear management!
You will either change employees to sighted and adequate ones, or close the department.
It's not the first time I've tried to hand over currency, they come up with excuses from the head. It feels like they don't know how to use technical means of checking bills, you see a shadow of doubt and confusion in your eyes, and you are analyzed by appearance.
And every time you go to Trinity and calmly change money in another bank without any questions, and they do not find defects there when you ask a question, maybe something is wrong with the bill. They kindly reply that everything is fine.
Pay attention to the competence and professionalism of your employees, trust in the bank is very undermined by such situations.
