Walking around barefoot is unheard of in Italy unless you are at the beach or swimming pool. Even in the house your host family may offer you a pair of slippers to wear! Drinking to excess is strictly unacceptable! Italians will drink wine and beer with their meals, have a glass of limoncello and put grappa in their coffee, but you will never see an Italian vomiting in the street. It is so not cool, and such behavior makes you and your culture look bad. You must remember that while working for ACLE you are not only representing the company but also yourself and your country. Everyone will know who you are and who you are working for and where you come from.
