They might have a hard time finding decent candidates at or near minimum wage. All the restaurants, fast food places, and convenience stores out my way have "Help wanted" signs, but the typical stated pay is no more than ~$12/hour (seen on a McD's sign). Warehouse operations and the likes of forklift drivers aren't necessarily much better off.
It's stupid for a business owner to complain about being unable to find good help when he's offering only minimum wage, part time, and no benefits. I've known of a few who did just that. Then they had the gall to complain about the quality of applicants and workers. Duh.
As a rule of thumb, the places that have lots of turnover and are always seeking workers are usually bad places to work. People leave for a reason, or the company is quick to fire over bogus stuff. Usually "easy hire" means "easy fire" (job termination).
