What cultural faux pas should I try to avoid making in Altea?

"In Altea, it is important to be mindful of local customs and etiquette. It is considered rude to be late for social engagements, so it is important to arrive on time. It is also important to dress modestly, as revealing clothing is considered inappropriate. Additionally, it is important to be respectful of religious customs, such as refraining from eating pork or other non-halal foods in public. Finally, it is important to be aware of the local language and to avoid speaking English or any other language in public, as this can be seen as disrespectful," said another expat in Altea, Spain.
