Girl, 18, to ask that I am slightly worried before not a month I started working in a hypermarket, I am at checkout and since they let me work alone went 7-8 days. I know that one of the most important things is to get your cash register out and that's my question, a few times it happened not to come out with some small amounts 2 and something np, but there was also once with 8 BGN and 13 euros. I'm just asking if it's normal to make mistakes like that at first.
