I was so enraged that I did my absolute best customer service. I talked loud and clearly, I was laughing and joking with customers, I moved through the lines quickly, I was everything I didn't think I could be on the register. I was enraged that I had a talking to by the boss because my coworker complained, but after addressing my issues with my coworker it turned out she was rightfully upset and I was in the wrong (although in this case we all were) but I kept up the momentum and I was received so well by the customers because I was so outgoing and friendly that I realized I need to channel this energy every day.
