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

"In Genoa, it is important to be aware of cultural norms and etiquette. It is considered impolite to be late for appointments or social engagements. It is also important to dress appropriately for the occasion, as dressing too casually or too formally can be seen as disrespectful. Additionally, it is important to be aware of the local customs and traditions, and to avoid making jokes or comments that could be seen as offensive. Finally, it is important to be respectful of the local language, and to avoid speaking English or any other language in public," remarked another expat in Genoa, Italy.
