I work part-time in a restaurant, and my co-workers are a mix of older and younger adults. I tend to speak more with the younger adults at work because they are closer to my age.
I work with an older woman at the front, and find her very annoying. She is rude and nosy, and makes a lot of comments that are unnecessary, sometimes they are invasive to my personal life. She tries to avoid speaking to me as she knows I don't like conversing with her. She'll then complain to my co-workers that I never talk to her, etc.
I brought in a cake to share with my friends at work. Since it was a fair amount, I decided to share with whoever wanted a piece. I didn't see her around the area me and my co-workers were sitting at, so I distributed the cake to whoever was present. I then hear from another co-worker who tells me that the older woman was complaining to someone about how I didn't offer her a piece. She wasn't around when I was serving the cake, and I had assumed she had already left. She never asked me for a piece either. It may seem rude of me to not consider her, but I don't really think I have any obligation to give her my food if I don't want to, considering the rude things she has said to me.
Was it rude of me to not include her when I was sharing my cake? I don't want to be a workplace bully if this behaviour is representative of that attitude.
