Supervisor: "You made an impetuous decision when that customer asked for an account credit."

Yes, I wanted to take my time and research the customer's account first.

I didn't realize that I was being hasty.

I always try to separate my emotions from the decisions I have to make.

I wasn't trying to be unkind. I'll try to be more sympathetic in the future.

Maybe I was a bit too generous. Thank you for the feedback.
