Should I quit or wait? 10 POINTS!!!!!!!!!!!!!!!!!!!!!!!!…

I just started as a teller at chase and now it is my third day there. The recruiter did everything at the last minute and now for the past two days I have been sitting on a chair for eight hours doing nothing because my training will not be up till next week. I realized since this branch is only open M-Fri, I won't be able to go to school full-time and that will be a big problem because of financial aid. Anyway I also was offered a position at Best buy which is 10 minutes close to home rather than the hour I have to travel to Chase. Now today is Thursday, I started Chase on Wednesday should I continue to work at Chase until Best buy calls when I am cleared for orientation or should I just quit right now and not come in tomorrow. Please help! Any advice would be appreciated.
