I didn't get a chance to read it either as they've taken it down but from the posts that I've read, if he wasn't in the Apple line trying to buy the entire store to resale to same customers, then I have nothing to say about this person.
Very different scenario but seemingly the same concept:
I went to a toyota dealer a while ago with my daughter to look at some camries. The guy was going through his usaul spiel and then I asked him, "hey didn't toyota conduct a recall for this model?" He replied with "yea, it was because of the floor mats." I just smiled and told my daughter lets move on. No harm, no anger and infact I laughed. I wanted to so badly ask him, so you mean to tell me that toyota recalled tons of cars and lost boat-loads of money because of floor mats?!
So if this guy wanted to make a dime on someone that had the capacity to hear, disect, rationalize and decide on the offer and go for it, that's totally up to that person.
