File this away: you never know if it might be useful to you someday:

If you ever find yourself in El Burgo Ranero, in the middle of the (far from the ocean) Spanish plain, and if you go for a “pilgrim dinner” at the restaurant across the street, and if you are offered a choice of the salad and the fish soup…

Do not order the fish soup. I repeat: do not order the fish soup. Do not order the fish soup…

This will be my mantra for the day.
