divebuddy - //I'll just repeat what I said earlier and leave it at that. I think where somebody's home is concerned the normal "rules" shouldn't necessarily apply. //
Absolutely.
You can have whom you want to stay in your home, and whom you wish to refuse.
But if you open your home as a business, then you are subject to the laws that govern that business.
You don't get to revert to the notion that it's 'your home' and you can refuse people, not even if you 'make a few quid'.
If you are running a business, then the premises is a business premises, and the law applies.
If you want to treat it as your home, then don't charge people to stay there, and you can say who stays, and who doesn't.
But the idea that you can slide between business and home depending on whether you like the people who come thoru8gh your door? Sorry, that's just not how it works.
