Easy , whilst in Fulham , I went to buy a parking ticket from the nearest machine ,when i got back with a ticket I had a an FPN on the screen , the CEO is supposed to log the time he spotted the van and allow the allocated time for the driver to return , he hadnt , I collared him just along the street,
, he waived his hand without a word in complete indifference,
so I appealed , and complained of his less than attitude , they pulled it the next day ,
