My brother in law works in one such place.I think your friend needs to look at his CV or the way he puts himself across. What is he applying for? There are literally places you could walk into and get a job pretty much same day.
The problem is it's hard work, it's not massive pay (above minimum wage with some pretty good OT and OT opportunities as they're chronically short staffed), and it's rotating shifts.
Brits tend to apply, last a few days and give up as it's hot, hard work (although apparently it gets easier once you get used to it and learn how to do the work in the most efficient manner).
