Just finished training, first week on drawer and I’ve been out of balance twice 😭

Today was BUSY. They called me in early because of how busy it was and I decided to go in and help them. I had a guy bring in $44 in quarters and when I balanced not long after his transaction I was over 25 cents so I deposited that to his account. Then towards the end of the day, everything was going smooth until this mess up.

I bought $2000 from the vault and somehow I entered $4000 instead 😭 I found that out when I balanced again and luckily my manager was SO kind and fixed it but it took us awhile to figure out what I did. Then at the end of the day I was $10 short. We couldn’t figure out where and how because it was so so busy. My manager kept asking if I was okay but all I wanted to do was cry. Has anyone had bad days like this? He kept telling me it happens, it’s okay but I can’t stop being mad at myself for feeling like I did a horrible job. I excel in the customer service part, I love talking to clients but with the banking side I’m struggling.

Any tips? Can anyone else relate?
