As someone who worked in Kitchens/Hotels/Restaurants from about the age of 14 to my mid 20s - I have never not been able to find people hiring KPs etc in an area. Low skill low paid work always seemed to be available.

Note, I was usually in _relatively_ affluent parts (the south) of the country. However after that I've always felt that should things go tits up I could always go back to 50+ hours a week on min wage...

Worth noting, even if I could do that I sure as hell wouldn't have the motivation to job hunt in my downtime.
