Tipping: It is customary to leave a tip in restaurants (10%), for hotel chambermaids, in reception for hotel staff . Taxi drivers do not normally expect a tip, but they do appreciate it, and it's acceptable to "round up" the fare. So if you're charged 4.5YTL it's usual to give the driver 5YTL. Hairdressers also get tips, similar to the UK.

Visiting mosques:  Both men and women are expected to wear clothing which comes to below knee level and to have their shoulders and chests covered.  Shorts, tanks tops and halters are completely inappropriate.  Women must cover their hair with a hat or scarf, and men should be bareheaded.  Shoes must be removed before entering the mosque, carry them with you unless you are with a guide who instructs you to leave them outside.  Many of the larger mosques provide plastic sacks for you to carry your shoes in.

There are usually signs which indicate whether picture taking is allowed; pay attention to whether flash is allowed.  Do not aim your camera at anyone who may be praying. 

Do not enter a mosque during a prayer service, wait outside until it is finished.  

Etiquette

Please as tourists remember that this is a largely Muslim country and modesty is appreciated. In restaurants it's expected that men will wear at least T shirt and shorts and women to wear more than beach wear. It is also more polite to cover up a little when shopping etc. If you come from the beach at least wear a sun dress over the bikini or shorts and a top.

 It is totally normal for men and women to greet each other with a kiss on each cheek and a hug and will often walk around arm in arm regardless of gender. This is a natural expression of affection.When greeting people shake the hand of the eldest person first. You may also see/ experience younger people kiss an older persons right hand and then put it to their forhead. This is a mark of respect for the older person.
