I was going into a pub and slipped on spilt beer at the entrance. I asked the landlord why he hadn’t mopped it up, but he told me the brewery had sent him a letter saying to leave well alone: it was an “Act of God”. Surely that’s no reason to leave a hazard on your doorstep?
I would say the brewery gave the landlord bad advice, if it’s true. Shopkeepers, licensees and householders have a duty to take “reasonable” care to ensure the safety of people visiting their premises or properties. If the landlord knew, or ought to have know, that people were slipping at the entrance to the pub he should have done something about it. Anyone injuring themselves might be able to bring a claim for compensation against him (or possibly the brewery) if he ignored the problem.
