There's this new person at work. She work next to me and we get along, but she's always asking me to do things for her. For example, she asks me to get her coffee when I get some for myself.Or she drops by and asks me to copy things for her when she's "busy". She's not my boss!Should I just refuse to do things for her? I want to be nice, but I have to do my own work. Can you help me,please?
