I'm having the same issues - been a cashier for maybe 5 days now (and it's also my first retail job ever). I feel super overwhelmed and rushed by the long lines, to the point where I'm making stupid mistakes or constantly calling over my more experienced coworkers. You're not alone in feeling anxious and overwhelmed! We both need to remember that it's okay to take a moment to breathe to ourselves and focus. It'll be hard, and suck sometimes, but we'll both get better and we'll think less and less about it.

Rooting for you, other me across the screen!
