that picture means nothing.. IF the economy was strong.. there might be 10x more people in line OR more retail outlets would be profitable around the city, not to concentrate all the consumers so line would be smaller. conclusion.. you can't predict if line would be longer or shorter and even revenues are hard to predict because maybe a competitor would have come out with product that grabbed market share, but in reality never had the opportunity because of market conditions.
I am married to a European. They text because it doesn't cost much compared to talk. In the US I don't get it. Texting is lame sorry. Besides in Europe most ride public transportation so texting is more practical.
