Expect it to be very fast and intense for a few moments and then incredibly slow and boring for most of the time.

Okay so i start my first day at work tomorrow at saint vincent de paul in slinger. Im really nervous and i dont know what too expect. Its going to be my first job, and its everyday from 12:30 to 7:30.. My first part of the day ill be getting trained on the cash register. Then the second part im getting trained on the floor. So my question is anyone who has worked in a retail store is it hard? And what should i expect for my first day? Will training be easy? Please answer:( and no rude comments.
