But if OP isn't hurt, why try to get anything out of it? It just doesn't seem right to me. I get that s/he could have been seriously injured, but s/he wasn't. I think the manager should be told that the cleaner laughed, but after that OP should move on if there were no injuries.

They'll likely still be a bit bruised. Just because they didn't break a leg doesn't mean they're not hurt. Either way, as you said, just because someone wasn't badly hurt this time doesn't mean they couldn't be. Such behaviour is dangerous and should be pointed out. OP doesn't have to insist that they should have free stuff, they just need to bring the problem to the manager's attention and they'll likely get some kind of freebie as a gesture of goodwill. It's not exploitation, it's just how good companies keep customers.

What about when people make the spills and don't tell anyone? There are plenty of times that has happened where we have the same policy where I work. I've been VERY lucky that I saw them before someone slipped. Honestly most slips people have are not paying attention to their surroundings.

Hmm, good point, I never thought of that. Usually I hear the smash or there's just enough people around that someone sees it...I actually have no idea what you'd do if you were in a large shop like that! However, in this instance someone clearly knew because they were bringing a sign.

Exactly, I agree, but even with a wet floor sign some people just don't listen and when they hurt themselves they want to sue. At my job people do this all of the time, they clearly see the sign, but still walk on the wet floor and get an attitude when you tell them to go a in different direction.

People like you are what's wrong with society.
