Lots of people die in traffic accidents here because they don't wear their seat belts. Police officers don't wear seat belts when they're driving. Major building work in a town centre will often have JCBs dodging around the milling shoppers. Safety gear is still a bit mamby pamby for most workmen. The sign says "Keep off the Grass" yet the grass is littered with picnicking families. Dogs must be on a lead - and of course they aren't. Parents snatch the sticky sweet papers from their children and throw the litter to the ground. Standing at the threshold of a (non smoking) bar, fag in hand, and popping in to emphasise your point in the discussion is commonplace. Double and triple parking, parking on the pavement or on a zebra crossing is endemic. Groups of people often re-organise the furniture on entering a café. Even the coffee order is anarchic - strong on coffee, short on milk, with sweetener and in a glass. There are lots more examples - I could go on; Maggie says I do.
Sometimes it's surprising, sometimes it's hilarious, sometimes it's nettling but it's definitely very Spanish.
Oh, and I think it's excellent that Spanish people often sit down to eat at their tea at ten in the evening too.
