Eating and dining Meals are commonly laid in the table centre and shared. Always accept a drink offer as it's a show of goodwill. Don’t insist on paying if invited out; it insults your hosts. In restaurants, service might feel slow; dining is a drawn-out experience and it's impolite to rush waitstaff.
Photography In churches, avoid using a flash or photographing the main altar, which is considered taboo. At archaeological sites, you'll be stopped from using a tripod which marks you as a professional and thereby requires special permissions.
Places of worship If you visit churches, cover up with a shawl or long sleeves and a long skirt or trousers to show respect. Some places will deny admission if you're showing too much skin.
Body language 'Yes' is a swing of the head and 'no' is a curt raising of the head or eyebrows, often accompanied by a 'ts' click-of-the-tongue sound.
