According to the article, it seems the kids of Restaurant owners don't fancy the work, and prefer to claim benefits.
Quite the sweeping statement of course, and definitely the opinion of just one bloke (I suspect he has a lazy child in the background somewhere!)
I think that's a bit of a shame. Restaurant work is hard graft for relatively little money, but I found it was a good motivator for me to buck up and seek better employment. Then again, I am a bit weird.
But for Students, many restaurants have casual staff, and those roles work for Students. Being casual you can turn down shifts if your studies demand it, and the relatively inconsistent earnings are less of a bother than to someone with rent to pay etc (student rent often being covered by their student loans. Which is a subject I'm not gonna start on here, because that's nowt to do with Europe!)
