People who say this don't think things through.
If it's supposed to just be work experience, how are the employees supposed to live while earning it?
I know, I know...no adult should be working there since it's a job for college kids or some other claptrap. Because every coffee shop is conveniently located for college students to get to work. No coffee shop would ever need employees at times that might not be convenient for the college student crowd.
And those non-college student employees don't need a livable wage because "coffee shop barista" is a jumping off point to some unknown high wage career that will magically become available within 6 months of landing a job at the coffee shop. (I head Goldman Sachs and Tesla regularly recruit from Dunkin Donuts because of the massive experience they get.
)
People really should think beyond the superficial throwaway phrases.
