My side hustle

So, I’m 18. I work for the financial aide office at my school. To put some money in my pockets while I’m in school. But I also have the opportunity to work at hooters. My mom hates and actually looks down upon girls who works in environments like that. So I plan on keeping it from her. I really need this money. I need stuff for school and with them already paying tuition and getting grants and stuff I still need it. I just don’t know how to hide this secret. Especially when I’m living under their roof.
