This person/ring of people, is probably earning at least the minimum wage, without being taxed. Shop work pays about ?5 an hour doesn't it? - if she manages to scam around 5 people a day, Monday to Friday, between ?5 and ?10 a scam, some people being more generous than others - she would be doing quite well relatively, and her time is her own. This person has made a decision (considering the amount of years this has been going on) and has honed her skills to become a 'success' at what she does. A shame, as given the right opportunity it sounds like she could have ended up on the stage...thanks for the warning, we shall be prepared should she stage a scene outside our front door - perhaps a round of applause would do...
