I was speaking to the proprietor of a small independent pub last year. He has two premises; one he owns and one he leases from one of the premises "chains". As it happens, neither is co-located with a 'spoons, and his food is excellent; so it's not intended as a comparision.
The reason for mentioning him is - in the leased property he can do pretty much as he pleases as regards food, but he is tied to buying drink products from the chain. We discussed Peroni draught. He is required to pay about £1 per pint more for Peroni at the leased premises than it costs him at his own place (where he is free to choose supplier). Hence he has to charge a minimum of £1 more per pint retail. One presumes therefore that in many places where independents are near to a 'spoons, the same things go on.
This is the sadness: these premises chains appear to be guilty of a practice that (artificially) inflates bar prices. You end up paying for their profits. Now, given that (in my experience, every single time) drink sold at 'spoons is always in good condition, and is invariably noticeably cheaper (for the same product where a comparison can be made) than is typical elsehwere, the question is - why would you pay extra? What are these premises chains doing to earn your money? Would you buy your (identical branded) baked beans from an unnecessarily expensive store or from the cheaper store nearby?
And places close. Not necessarily from bad proprietors; from lack of trade driven by inflated prices which is in turn driven by the premises chains practices. There is a lesson to be learned - and it doesn't appear to be being learned. I find myself - not through any wish to disadvantage the proprietor himself, but from a reluctance to fund these premises chains from my wallet - often choosing to drink water with my (good) food.
