I want to shut down the atm at work in the middle of transactions if the person is rude to me or my other customers.
Why would you shut down the ATM because of that?
I don't like when customers take out their bad mood on me.
I understand how you feel, but it's not appropriate to shut down the ATM just because someone is rude to you or other customers. Taking revenge on them isn't the best way to handle the problem. You should act politely towards them because it isn't worth getting upset over.
Fuck that, I'm going to do it.
You might lose your job if your boss finds out how you've been treating the customers. Working in customer service can be frustrating but try to keep a cool head. Talk to the customers and smile at them, when they see how friendly you are, they might be friendly back to you.
