Such toilets are typical to the Eastern countries. You will likely find them in China, Russia, all Middle East (huh, including Egypt) and Africa. Then it looks like more than a half of the world uses such "hole" type of toilets

Nowadays as a Turkish integration example between east and west we use toilet paper.

But we didn't forget the water. There is a 4 steps process. Step 1: Use toilet paper. Step 2: Use water. Step 3: Use toilet paper as a dryer for known areas. Step 4: Use soap and water for hands and than get much cologne as possible.

We use for this left hand. For that reason we never use our left hand for eating something directly. Many religious people never eat with left hand even if with fork or spoon.

PS 1: This integration idea is not mine. I was read it in an Engin Ardıç's book (who famous columnist in Turkey)
PS 2: How did the matter come from "street food" to "public bog"? Can anyone tell me? If its foods hygenie matter than I must to say that Hepatitis and icterus never seen at Turkey over the world average.

Hmmm, I couldn't help but respond to the discussion on the toilet issue...though this thread is "Turkish Street food". (Maybe someone should start a new thread on "Toilet culture" )

When comparing to toilets of many other countries, Turkish ones are clean. Of course, Japanese toilets are always the champion on cleanliness. In fact I find the water supply next to the toilet seat or inside the toilet seat is a very good device. Toilet paper, rinsing water, toilet paper and then soap and water for hands is a more thorough cleaning process. It should be more hygienic too provided that they really clean the little tap inside the seat from time to time.

Once a Turkish friend asked me when visiting Hong Kong, "why there is no water tap at the toilet seat? How can you be clean just using toilet paper? We..there...are hairy..."
