The weird part is I am starting to expect people to be unresponsive, fickle and unpredictable at least, due to my dealings in the BTC sphere. It is the only place in my life where this sort of behavior is tolerated, even rewarded. Its starting to bleed over into my real life too. People talk to me and I walk away while they are half way through speaking. I stand there and appear to be listening but I have not, and I have no reaction whatsoever. I will live, life will go on, everyone will figure it out eventually...why bother?
It depends on who you're dealing with. Most of my transactions (dated a while back) not even needed escrow (some of my friends I've dealt with, now offer escrow services themselves, as we speak). There was a certain individual though, that forced me to abandon a deal. He was trying to sell a laptop but wouldn't let me see pictures, nor use an escrow service, or even accept to have 10% upfront then send the item and after I received the photograph of the package on the post, pay the rest.
So to sum up, it depends.
