@Angel23,
Angel, please go back and read the many posts you wrote under the dirrtydozen22 name, especially the ones where you got fired from Walmart for your overreaction to someone not wanting to be friends with you. Then read the ones from the fast food place, I can't remember if it was McDonald's or Burger king, where the same thing happened with your supervisor there. You obsessed to the point that it got you fired because she was no longer willing to be friendly with you. You did the same thing at another fast food place.
Now you are doing the exact same thing at Costco. Your inappropriate behaviors force supervisors to treat you differently than your coworkers and then you obsess on the unfairness of that when it is your behavior that caused it to happen in the first place.
You are repeating the same exact thing again. If you don't get this under control, you are going to lose your job over it when your anger gets you in trouble again. This has been a very good place of employment for you. They have been very tolerant of your behavioral quirks and have given you many chances beyond what most companies would do. Don't blow this. You are running out of employment options. Do whatever you need to do to finally understand what we have been saying to you for many years. We want to see you succeed. You won't do so if you allow yourself to keep going through these behavior cycles of yours without learning anything and changing your actions.
You have the power to make this have a different outcome this time.
