I visited Istanbul earlier this year, and it amazed me how bargaining and selling was so ingrained in the culture. Every store, every restaurant, even the hotel... it's just a different way of dealing with customers.

And here in Canada/USA, some stores have sales people that don't want to disturb you. They sit quietly in their chair in the back of the store, don't dare approach you, and don't speak until spoken to. That's not sales, that's "question answerer".

Real sales has an active component.
