So, you came early - we didn’t have the kind of communications you have today. Everything was more difficult. It started with the telephone call. Today, you ask for a connection, in half a minute you are talking with Japan. In the past, sometimes you requested a connection to Spain, but they would only answer at night. Communications were much more difficult back then. Now, you have all these new types of communications and everything. So you paid for the lot of coffee that needed to be sold. Your customer met with you and said: "Look, I need to sell this lot of coffee." Let's say, from Campinas, from Franca, or where ever. You paid for those samples from the interior, samples of coffee, leaking, everything just right. You put it on the street, roasted them, in various places - even today, many houses working with coffee - they toast and classify the coffee. In the afternoon, after lunch or the next day, as had been agreed to, you went there and he gave you the coffee. If it was more or less what you thought, you pass it on to your customer, by telephone, or by telegraph, understand? Then you wait for their answer. It works or it doesn’t. Let's leave it for later, the market will be better. (Eduardo Hayden Carvalhaes, 2011, p.5).
