Will a warning sign impact my slip and fall injury claim?

We have a client that was involved in a slip and fall case in a restaurant. He walked into one of the entrances of the restaurant, took a couple of steps, his foot hit wet floor, and down he went. As we were discussing the case with the insurance company, the insurance company said, “Your client doesn’t have a case because we had a caution sign out that said there was a wet floor.” When we looked into it further, we discovered that the wet floor sign was over by a separate entrance, where it would’ve been very hard to see for anybody, including our client who was walking through the other entrance. We helped him understand that, in this case, even though there was a caution sign out, he does have a case against this restaurant.
