Job advice!!

So I’ve worked at a grocery store for almost 2 years making minimum wage @$8.60 per hour 🙄. I work about 30-35 hours a week & with this job I’m required to work every other Saturday.

I applied at the post office near me & I have an interview coming up. They pay $17.85 per hour BUT you start out only every Saturday of the month until you learn the routes then you get more hours as you learn. And It is part time.

If I get accepted at the post office job I won’t be able to keep the grocery store job, what should I do??
