I have a prepaid legal membership as well as identity theft shield. What I liked was there was no contract if you felt you didn't need them you could cancel your service. I am not someone who feels they "need" a lawyer to get through life but I tell you what, having them I've run into situations where it was nice just to have someone to call who actually gave real legal advice.
I believe in them so much I became an independent associate and definitely encourage people to use them as a supplement to help keep the regular lawyer bills down.
You can see a bit more about the coverage you get at my site.
I hope this helps greatly!
Unfortunately if your injury is extensive, you will have to obtain the services of a good personal injury lawyer. In terms of the sign -- yes it can help mitigate their liability but it does not in and of itself absolve them of liability. Quite the contrary -- the sign helps to prove they are liable, i.e. they knew that the floor was wet and that it presented a slip and fall hazard. They should have put the bathroom out of order until such time as they could fix the problem or dried the floor immediately if it was just a case of spilled water. If the floor was wet because they had just mopped it, then they should have scheduled the mopping at a time when it would not present a hazard to the public.
All businesses that are open to the public have a duty to provide a safe environment at all times. Further that sign should have been posted on the door at eye level and the manager should have showed you some type of concern as in inquiring if you were injured and/or in need of medical attention, taking your information and writing up an incident report, etc.
I hope this information helps and that you recover fully. Good Luck
