Go for that job. It gets you back home and you don't manage a McDonalds. You don't even supervise. You have a very very specific skill set, hence why you had to take a job hours away in the first place.
Take the opportunity and apply for this job and let her know, "OH, yeah, I already knew about that job before you sent it to me, but thanks though."
Get back home to your boys CIPA. This is a no brainer.
