Do you understand?
Lots of Spanish men have grey hair and quite a few are as tall as I am. My clothes come from Spanish shops and I have my hair cut here. Nonetheless people recognise me as a foreigner long before I speak. I too play the game of recognising Brits in the street. I'm often right though I'm far from infallible - sometimes they're Dutch, German or Belgians but mostly, when I get it wrong, they are Spaniards. Last night we went out to get a couple of drinks and eat something at one of the Cruces de Mayo bars. As is so often the case at fiesta type events we had to buy tickets first and then hand the tickets over at the bar in return for the food and drink. I suppose it centralises the cash handling, increases security and also leads to a slight over-expenditure on the part of the customers - just to be sure. We joined the scrum at the bar. For once I wasn't too worried about shouting my order through the din. At the bar, there were price lists everywhere...
