I think anyone being asked or wanting to store something can use this thread as a good resource to the many cons compared to the few pro's...
I was a bit tongue in cheek with the remark but if things go legal anything can be used to stir the pot until the person with the biggest legal fund typically wins.You, or the bank, can put anything you want in a document or contract... it doesn't mean it is legally binding.
Both side of a contract have in-alienable rights that no "waiver" will change. You can't sign away your rights, nor can a document add to your rights.
sameSpeaking of storage facilities, maybe you should get a sample from them. That's pretty much what you're doing. My friend mentioned that his included a clause that stated he had to have his own insurance for his items (including the bike), since they would not cover damage, theft, etc.
