Street vendor

The xendors carry their wares on a big square sheet attached at the corners with ropes.
They operate in groups, constantly on the look out for police.  An audible alert is sounded when police are near and the ropes draw the sheet into a bundle which is quickly thrown over the shoulder for a rapid escape.  Within a few minutes they are back.  

Today I chatted to a mother and son visiting from Newcastle.  Mum was in her late 50's and still enjoying music festivals.  They both liked heavy metal and rock music  I also learned about her varied pet and skull collection
