You've come a long way in 16 days. I'm sure you had fun.

I fondly remember this moment when we stopped in an unknown Turkish city, in a roadside cafe, to eat our favorite lentil soup. Three servings for only $7, and bread + tea for free. I love this Turkish tradition!>

$7 means approximately 240 TL. 4 years ago, it was possible to drink this soup for 50 TL. Tea is free in most places. When you serve something to a customer, a sense of belonging is created. A useful tradition.
