Why tho?? There’s so many on campus jobs that pay more and you don’t need to commute there. Work in your library, work in your colleges convenience store, become a tourguide, do research, work as one of those people whose job is literally to call alumni and ask for money … the list goes on
Just wanted to say that this is not universal. My school pays peanuts compared to what an off campus service job in the area will. Also, might not be the case for OP, but my school caps the amount of hours they’ll let you work on campus per week (15 usually), so since they’re already a TA, their school might not let them have another on campus job
