Thank you for the above replies. Hopefully, I will get a different job in the near future. My coworker's spaciness is really annoying. Today, she had left me a note "fold the sweaters, they should be there". What the....??

Plus, she asked me how I was doing with the customers, and asked whether I was "afraid" of the customers. I said no, and she again repeated the question, and said how she used to be afraid of customers when she worked in restaurant work, and was going on and on. I admit that I am an introvert and do not like to make a lot of small talk with customers, other than what is really necessary. I don't like talking a lot because it is annoying. I consider myself a good listener and that is much more important than annoying a customer with nonstop chatter (like she does). God, I wish she would SHUT UP.....
