Hummm…..extortion....really?
Maybe you are correct and I shouldn't try to use it as "leverage". However, I don't see how there isn't any "leverage" yet. Maybe it all depends on how it’s phrased and/or proposed. /shrug.
If I commit a negligent act, which hasn't resulted in any damages yet, but has the potential to do so. Then the potential person/s who could be damaged in the future came to me and said, give me $5 and if there are damages in the future (which is very possible) as a result of your negligence I’ll waive my rights to sue you at that later date for those damages.
I most certainly would take them up on the offer and I wouldn't consider it extortion.
