I Don't Get It!

Okay so the other day I called my boss to see if he had gotten my note, then he said I needed to come in so we can talk. then he tells me that he cant afford us getting auditted so he lets me go. BUT GET THIS! 2 weeks prior to that another person came in 45 mins late for a meeting, when the same person that was late said that the meeting had a hard start time of 6'oclock. Then after the meeting he goes to the manager saying it was disrespectful to start the meeting without him, and then he says suspend me fire me whatever I am leaving. but that guy still has his job and I don't I mean I dont get it. You can cuss out the GM and still have a job but for auditting purposes, I dont. I am kinda glad I dont work there anymore, it's a popularity contest.
