Public drunkenness (especially the loud and obnoxious variety) is
definitely not appreciated and is frowned upon, especially in more conservative
areas of the country. Drunken tourists may also attract the attention of
pickpockets. However what is absolutely not tolerated with drunkenness
especially by the police, if it is accompanied with physical aggressiveness
towards other people, this may result with a fine and if this is repeated a
heavier fine and/or a visit to the police station may result (if you are
tourist, deportation from the country can result).
Certain gestures, common in the western world, are considered rude expressions
in this culture. People tend to be tolerant if they can see you are a
foreigner. They know you are probably doing it subconsciously, but if you take
the time to keep these in mind, you won’t have any misunderstandings. Making an
‘O’ with your thumb and forefinger (as if to say “OK!”) is rude because you are
making the gesture for a hole - which has connotations referring to
homosexuality in the Turkish psyche.
Avoid clicking your tongue. Some people do this subconsciously at the beginning
of a sentence. It is a gesture of dismissal.
Also the "got your nose" gesture which is made by making a fist
and putting your thumb between your forefinger and the middle finger is
considered the equivalent of the middle finger in Turkey.
Do learn gestures of the head for “yes”
and “no”, which can be very confusing. “Yes” is a downward nod of the head and
"no" is an upward nod of the head while raising eyebrows and clicking
the tongue. Shaking your head might not be understood as “no”. Try to learn the
Turkish words evet (yes) and hayir (no).
Do take off your shoes before entering a
home. Do bring a modest gift. Keep in mind that many Muslims adhere to an
abstinent lifestyle – a bottle of alcohol is thus not an ideal gift. Giving
money is considered rude.
Do bargain. It’s regarded as a polite
gesture and a form of dialogue to negotiate the price before buying.
