When I started working here, I was confused what I was doing and I got scared but I overcome those weaknesses by slowly working and understanding the concept. For my experience, it was very simple task, for instance you always need to help the customers with their purchases. I always had closing shifts and you will always feel tired after cleaning up the mess, such as the clothes, mopping and checking other stuff. The management was a bit off, since retail stores are always highly strict. I've learned that you can handle customers how they behave and act. The only most enjoyable part of this job is when the store is not busy and you can chat along with your co-workers.
Overall, I think it's a great place to work, except if you're looking for a full-time job, this isn't for you.
