Guess this is human nature. I've been in sales and marketing for 4 years and during my S & M (err... that's not what I mean) boot camp they call this behaviour fishing (pardon the pun). For instance, picture yourself buying a handphone. You go to the store, the sales guy attends to your questions and even shows you the phones. When asked which phone you want, the standard answer would be, I'll think about it first, or I'll walk one round and come back later. Which will never happen. And this is repeated at 2 other shops. Motive? Not only to find the best price, but best discounts, best packages, best everything. But guys, this is not an Asian thing (nothing to do with Kiasu culture). This example was cited by a Mat Salleh from US!

Aren't humans interesting specimens?
