There are easier ways for someone new to the industry to get pitiful training, earn less than minimum wage, be treated like a slave, have to find your own relief manager to get a holiday, etc.
Much as I don't like Wetherspoons pubs, they treat their staff well, train them properly and prepare people for running a pub of their own, should they get the opportunity.
Still, even Sams would be better than getting suckered into a tenancy or leasehold at some dump that the likes of Enterprise, Punch, and Trust Inns etc are trying to wring cash out of because they can't sell it.
