The line of string was attached near to the station in Alcoy, Spain. This line acted as the safety cord in case a quick exit was needed from this unknown city. The chance of a stealthy 'vistazo' was removed by the string's presence. I had within a short time, unwittingly, trapped three elderly ladies against the side of a newsagents and caused a child to come off his scooter. This unknown city was growing impatient with this failing performance. 

Cut the string and run, was the only option.
