Etiquette

Religion Dress modestly and be quiet and respectful around mosques.
Hospitality Generous Turks take it seriously; you may receive a few invitations to dine or drink çay together.
Restaurants Generally, whoever extended the invitation to eat together picks up the bill.
Alcohol Bars are common, but public drinking and inebriation are less acceptable away from tourist towns.
Greetings Turks value respect; when meeting a group of people, shake hands with all, male and female.
Language Learn a few Turkish phrases; immeasurably helpful and appreciated by Turks.
Relationships Do not be overly tactile with your partner in public; beware miscommunications with locals.
Politics Be tactful; criticising Turkish nationalism can land you in prison.
Queues Turks can be pushy in public situations; be assertive.
