In Plaça de la Vila de Gràcia there is a bar run by a very angry man who looks like something out of a Coen brothers movie: "We haven't asked to see a covid certificate nor will we", he exclaims, masked in blue and red-faced, when he hears that this Friday is the first day that the covid pass is a requirement to access bars, restaurants, gyms and nursing homes. Next door, the owner of a family cafeteria is less irritated, but does not hide a certain helplessness: "I'm alone in the bar and either I serve customers or man the door, but I can't do all at once," he says. "Anyway," he adds, "I know the customers here, in general. And if I don't know them, I serve them first and then ask them": sometimes the order you do things in does make a difference.
