The word on the streets

When I go to the market at boulevard Richard-Lenoir on Sundays, I usually call in for coffee at the bar du marché. In these times of ongoing financial crisis, riots on the streets of Iran, etc., what are the topics of import being discussed at the zinc? 1) why is the renault car not doing better, when the Red Bulls are in positions 1 and 3 on the grid (for Silverstone today) and they use the same engine? This is the cause of much vexation. Subject 2) what is the size of a beer glass in Italy? It was contended that a small beer in Italy is typically 20cl, while a normal beer is 40cl. I could have provided some expert comment on this but obviously someone with the actual answers is superfluous to a discussion like this.
