I was a cashier a lifetime ago and I loved it. The first day was difficult, and I thought I'd never figure out the register, but the next day was a piece of cake.

What I like about the cashiers at PetsMart is that they always ask about my animals. I realize they are probably trained to do that, but they really seem genuinely interested.

I'd be willing to bet you will not only get the job but also enjoy it tremendously.
