Kiya, I did that, started a retail job and then quit because I didn't like it, right about this time. If it is not right for you, it's not right! Your experiences are supposed to be providing you information about your likes and dislikes. If you are surly :-) working with the public and your coworkers, how is that helpful to anyone? Don't feel guilty about quitting now, especially since it is early and they can probably get a replacement clerk easier. It's not going to get any easier, as you know!
