-- Using your eyes is the simplest if you feel a bit uncertain. -- See how the other guests behave. Everybody participates in a kind of theatre, where the guests, too, play their parts. That means that you are a part of the other people's experience, just like the others' behaviour is a part of your experience. That is why behaving properly is a way of showing respect for the others' experience.
It’s not that hard, really. Visiting a new and unfamiliar milieu. Like a luxury hotel, as the above quote (in my translation) refers to. Or a milonga in Buenos Aires. Or somewhere else.
