Never say Vacation as you will be laughed out of the saloon bar. We use cocktail sticks and not toothpicks ( they are used to spear very small sausages and helpless chunks of pineapple and cheese instead of being used to clean your teeth). On a persoanl note, when I went back to the UK in 2001 after 8 years here in Brazil I actually forgot that you don´t usually kiss female friends on the cheek and shake your male friends hands as we do here. My actions caused a few raised eyebrows I can tell you.
