Drinking coffee at the bar in the morning is a deeply rooted Italian tradition, and the terraces are often packed from the early hours of the morning. But Italians don't spend hours at the bar, and espresso is drunk quickly before going to work. As a result, the Romans may take a dim view of you if you quietly dip your croissant in the coffee for half an hour! In any case, dipping all sorts of things into your coffee, whether it's quick or not, is considered bizarre by everyone outside France, isn't it? The right thing to do is to drink an espresso (not eXpresso!) from the bar in two gulps.
