I get that sometimes from prospective employers. Last couple interviews (prior to landing my current gig) I stapled a copy of my birth cert to the resume. I was being tossed out as inexperienced before the interview really got underway.
One place I threatened to call DOL/Human Rights over the interview because they referred to me as a 12-year-old with a stolen resume.
Anyway, my experience with fast food joints (both actual and listening to war stories) its almost always the same. Starts out great then the summer ends and someone with no management skills gets put in charge. He or she hires "friends" and everything starts to slip.
The other failure mode comes from Mommy or Daddy Franchise Owner appointing Bobby or Sue Family-Member to a leadership position.
*shrug* So glad I don't have to deal with that shit any longer.
