Note that you are comparing a big chain store (Circuit City) with small business (a Turk). Most businesses in the US are small businesses, which behave differently than chain stores. And if you think that that the Turk wouldn't get back the price of his tea hundredfold when you buy that rug, then you're very naive :) It's just different styles of conducting business - in some cultures, the negotiations are supposed to be personal and simulate closeness and friendship (even if parties are hoping to cheat each other as much as possible), in some it is supposed to be businesslike and impersonal.
As for the Apple store, I had been a number of times in Apple store in San Jose, that's abut 15 minutes drive from main Apple campus. Almost each time I had the worst experience. I had to wait for a long time, workers kept redirecting me from one to another, and since the policy is that there are no lines in Apple stores, I had no idea when I am going to be served - I just had to aimlessly wander around the store and wait for the moment where some "genius" is ready to grace me with his attention. I had to explain what I need to multiple people, which for some reason didn't talk to each other, and I observed multiple store workers not busy with anything but somehow still unavailable to help me. I am totally unconvinced about that being the paragon of customer service.
Well, you're wrong about one thing: that's not just small businesses in Turkey. Even very large chain stores have the same level of hospitality. And it's not just stores. As an example, tomorrow is the start of Şeker Bayramı (literally translates as "Sugar Holiday" but is just what Turks call Eid al-Fitr, the end of Ramadan). The holiday lasts for 3 days. I received a text from Turkcell the other day stating that they were giving everyone unlimited texting during the holiday.
Edit: Also, of course the Turkish businessman is making back the cost of the tea. It would be foolish to think otherwise. The point is that (if you want to go all Econ 101 on it...) Turks tend to think in terms of straight profit, whereas Americans are much more obsessed with opportunity cost.
There are many more examples of stuff regularly given out by companies for free, it's just two things I could remember immediately due to you mentioning "sugar holiday" :)
Heh...you really do need to visit Turkey. Turkcell didn't advertise that they were giving everyone unlimited texts. There was no article in the national paper about Turkcell giving unlimited texts. They did it because it was proper, and hospitable. In short, Turkish hospitality is very different from the examples you gave.
Trust me, if you ever care to visit Ankara, tell me and I will show you Turkish hospitality.
(Or, as odd as it sounds, Anthony Bourdain's "No Reservations" episode on Istanbul does an amazingly good job of capturing the essence of modern Turkish culture...http://www.youtube.com/watch?v=4ojatA-Xqhk)
I have visited Turkey in the past briefly, and it was nice, though I did not notice any special hospitality not encountered in other places. Maybe I just wasn't lucky.
Off topic indeed, but this year's Eurovision singer from Turkey was Jewish (http://en.wikipedia.org/wiki/Can_Bonomo). Not to say there isn't anti-semitism, but I think it is much less in Turkey than you might think.
