Greetings Spaniards almost always greet friends and strangers alike with a kiss on each cheek, although two males only do this if they’re close friends. It is customary to say ‘Hola, buenos días’ or ‘Hola, buenas tardes’ (in the afternoon or evening) when meeting someone or when entering a shop or bar, and ‘Hasta luego’ when leaving.
Eating and drinking Spanish waiters won’t expect you to thank them every time they bring you something, but they may expect you to keep your cutlery between courses in more casual bars and restaurants.
Visiting churches It is considered disrespectful to visit churches for the purposes of tourism during Mass and other worship services.
Escalators Always stand on the right to let people pass.
