Is working as a cashier hard?

It was hard to stand up for long periods of time for me, and my back and feet would start to hurt. It got boring too, and working cash was definitely my least favourite of all the jobs I've worked. If you're switching around between positions though it should be less boring, and it definitely is fun to get to know the customers! The actual cash is easy to get the hang of, it'll take a couple days but it's not something to stress over. You pick up speed after a few shifts as well:) Good luck!
