Just because you are in a bad mood, it does not make it right to take it out on someone! I saw this a lot today. I get it I have those days when I am in a bad mood and yes I do take it out on people sometimes. I don't feel good about it when I do it, but that's why I am working on it.
People don't know what's going on in your life, so sometimes they don't know you're in a bad mood. Sometimes it's ok that you do backlash at someone, but today what I saw was just rude! Today there was a girl, not going to say where this was, but she came in to work her shift. She sat at a front desk and was just in a bad mood. Every time someone came up to the desk she would answer in a rude way. Then as they walked away the girl would say some remark to the people around her about the person who just walked away. I heard the F-word several times, which isn't that bad but she's working and there are people trying to do their work. She was so loud along with those with her it was kind of hard to concentrate. She also kept saying she didn't want to be there and how she wanted to be home. Go Home then. Tell your boss or something or quit! I don't know, but if you don't have a choice then just leave your bad attitude at home please. Some people weren't doing anything wrong but the way she was talking to them was very uncomfortable. I heard her call this one girl a B**** after the girl had left. She even got into an altercation with this guy, which I'm not going to go into to much detail about. Let's just say I heard her saying a cuss word or two. I thought he was handling it very maturely unlike the girl. She then later told her friends or coworkers, whoever they were, a similar version of what happened but made they guy look like he was in the wrong.
Anyways I'm getting too into what happened. It was just kind of irritating for me to see that someone can act like that at work. You should not treat people like that just because of your bad mood. Leave it behind somewhere please! That person you treated like shit, might become someone important. For example, they might be your boss someday! So remember it could come bite you in the butt some day!
