What sad things have you experienced in the workplace after graduation?

After working in a billiard hall for one year, my work attitude and ability (although this job does not require any technical content) have been recognized by everyone. Then, this billiard hall is jointly opened by four bosses, which is the premise. 20/kloc-in July, 2008, a regular customer (a cousin of the boss) came to play ball and left without giving me any money, so I recorded the account, came back to ask him for money, and told me rudely that you liked to close the table and turn around, and told another boss that I was aiming at him. After the boss came, I told him the truth. As a result, he asked me calmly, "Then why didn't he pay?" He came to spend money. Why shouldn't I ask him for money as a bar? He won't give you a boss, he won't speak for me, he questions me? Then he said to me, "detain 500 yuan." I just said, "I quit, okay?" Then I called the person in charge on duty, tidied up what I should do and left directly. In fact, this boss is only in charge of the accounts, and when I booked the ball before I made the bar, the bar told me that I would lose one or two thousand yuan a month and asked me to go to the bar to make up for it. It didn't disappear until I lost money in my account every day at the bar. Everyone knows that he took the money, and he can't say anything. Fortunately, my salary was paid two days ago.
