There is a moment that most Americans experience within their first few days in Italy that no guidebook quite prepares them for. It is usually around 1pm on a Tuesday, when they walk into a restaurant and are shown to a table, handed a menu, and then left entirely alone for twenty minutes while the waiter does something unhurried at the bar.
The American reflex is to interpret this as neglect. The Italian waiter, if asked, would be confused by the question. You just sat down. What is the problem? That gap in interpretation is not about service standards. It is about time, and what it is for.
