Mom paying me a favour

I work as a security at a casino and my mother is a a Black Jack addict, she spends a lot of money gambling. Last time because I've made a special request to my boss he let her go and pay her debt in several times. This almost cost me my job and my mother said she will pay me back, since she doesn't have money and the few she will get in the near future is to pay to my boss I've decided I wanted to get paid in a different way...
