What is the state and feeling of a girl working in a bank?

I have worked in a bank for more than three years. Let me talk about the feelings of those years. I was a front-line teller at the bottom of the bank, and I had to repeat a lot of business every day, including deposit and withdrawal. It is ok to deposit and withdraw large sums of money at the counter, but many people want to deposit 1000 at the counter and take 500. If you tell him politely at this time, please go to the ATM to access 20000. Many customers will say, I have arrived, please help me. What's more, they will clap the counter and shout, you are doing business here. You care about the scale of my business. Are you bullying me for having no money? Withdraw money, you give me 1 yuan, and I'll take it one by one ... and so on, some customers just make trouble. The reason why ATM exists is to reduce the passenger flow at the counter and make it available for some special business. If everyone does this, it will be meaningless for banks to invest in those high-end ATMs, which will only increase the time cost of customers who really need to go to the counter to handle business. After a long time, my heart told me that I had to argue with these customers. I'm not arguing with my clients, I'm maintaining the balance of my inner world. But on second thought, in this case, I'm afraid I will make an enemy with this customer. Will it make me more embarrassed when he comes to my window next time? Will you complain about me? Comrades who work in banks know that the leader will punish you whether there is reason to complain or not. Therefore, working in a bank is not only tiring, but also often entangled with yourself. Forget it, I don't usually care about this person. Forget it, pay attention to your image. After all, you are sitting in this glass cover and wearing a uniform.
