My husband's friend was a manager at a convenience store. Here's what happened:

Manager: "You need to get motivated."
Worker: "I do my job."
Manager: "Not really. I'll tell you what. If you get your ass motivated and work hard tonight, I'll smoke you up after work."

Manager reports later that "you have never seen anybody work harder in your entire life".

Manager gets fired. Employee gets fired. Business closes about a month later.

That's what you get for interfering in personal business!
