Advice
To anyone who is about to start a similar job, I would like to say that all the nervousness and anxiety you may be feeling is completely normal and will eventually be alleviated through experience and learning. During my first shift at register, when I was responsible for the store's and the customer's money, I was inevitably a bit nervous, considering that this was my first retail experience. However, as time went on, I began to open up exponentially and learned how to talk to customers with ease while processing their purchase/return/etc. I can honestly say this experience has broadened my social scope and has given me a lot of confidence in general.
