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

"In Puglia, it is important to be respectful of local customs and traditions. Avoid making negative comments about the local culture or people, as this can be seen as offensive. Additionally, it is important to dress modestly and avoid wearing revealing clothing, as this is considered inappropriate. It is also important to be aware of the local religious customs and to be respectful of religious sites. Finally, it is important to be aware of the local dining etiquette, such as not speaking loudly or eating with your hands," said another expat in Puglia, Italy.
