They have no responsibility ...Basically if you are expecting ANY material benefit from asking the other party for advice/their take when considering a contract you are a little more than drooling on your shoes.

Sure they do, if you're tricked its called fraud. Even if you're not tricked, it doesn't make everything you sign binding (see non-competes).

At the very least you get a feel for what type of business you're dealing with.

Then you thank them for their time, and go and consult your lawyer if you really feel you want to work for dicks.
